There is something wonderfully silly about the premise of Increbraintal. Somewhere inside the human brain, an army of tiny defenders is preparing to wage war against an endless stream of dangerous viruses. It sounds like the sort of idea that could easily become a throwaway joke, yet beneath the cheerful presentation lies a surprisingly satisfying little strategy game. Increbraintal does not try to overwhelm you with complicated systems or demand hours of your time. Instead, it understands that sometimes the most enjoyable games are the ones that let you settle into a simple rhythm, make a few clever decisions, watch things explode, and then spend your rewards to become a little stronger.
Developed by Hymoori and published by Hymoori on PC alongside GAME NACIONAL on Nintendo Switch, Increbraintal is an incremental auto-battler built around formation, progression, and the constant satisfaction of watching numbers go up. Your units fight automatically, so your attention is focused less on frantic reactions and more on deciding where your allies should stand and which upgrades deserve your hard-earned resources. There is a gentle simplicity to the whole affair that makes it remarkably easy to pick up. It may not be the deepest strategy experience you will play this year, but it knows exactly what sort of game it wants to be.
A Tiny War Inside the Mind
The core concept is immediately accessible. Your brain is under attack from viruses, and your job is to assemble a suitably capable collection of defenders to keep the contamination at bay. Rather than controlling every attack manually, your team handles combat automatically, allowing you to focus on formation and progression. There is something oddly relaxing about watching your carefully assembled little army go about its business while you consider what to improve next.
The automatic nature of combat will not appeal to everyone, particularly players who want their strategy games to involve constant decision-making. Here, the important choices tend to happen before and around each encounter rather than during the fighting itself. You select your allies, arrange them into a formation and look for combinations that allow their abilities to complement one another. Once the battle begins, the fun comes from seeing whether those decisions actually work.
That simplicity is also one of Increbraintal’s biggest strengths. You never feel buried beneath menus, complicated statistics or a huge collection of tutorials explaining systems you may never need. Everything is presented in a way that encourages experimentation. If something is not working, you can adjust your formation, invest in a different upgrade and try again.
Formation Is Everything
Although Increbraintal is an auto-battler, there is still a satisfying amount of thought involved in positioning your units. Your team is arranged across a tactical grid, with different characters bringing their own strengths and weaknesses to the battlefield. Some are more effective at dealing damage, others provide support, while certain units become considerably more useful when positioned alongside the right companions.
This creates a pleasant little puzzle before each encounter. You are not simply collecting the strongest characters and throwing them onto the field. Instead, you are encouraged to consider how their abilities interact and whether your formation makes the most of the space available. It is hardly an intimidating tactical system, but it provides enough decision-making to stop the game from feeling completely passive.
There is also a nice sense of discovery when you stumble across a combination that works particularly well. Watching a previously troublesome wave of viruses suddenly collapse because you have improved your formation is satisfying. It is the sort of small victory that keeps incremental games ticking along, particularly when the next upgrade is always just beyond your reach.
The Joy of Watching Numbers Rise
Progression is at the heart of Increbraintal, and the Skill Tree provides the long-term incentive to keep playing. Resources earned in battle can be invested in permanent improvements, allowing you to increase damage, health, range and economy generation. The system is straightforward, yet it gives every run a sense of purpose, because even a failed attempt can help make the next one more successful.
This is where the incremental design works particularly well. You are rarely left feeling that a run was completely wasted. Even when your defenders eventually buckle under pressure, you have usually collected enough resources to make some improvement. That improvement then feeds into the next attempt, which generates more resources and allows you to push a little further.
There is something almost hypnotic about that cycle. Fight, collect, upgrade, rearrange and repeat. It is not revolutionary, but it is effective. Increbraintal understands the strange satisfaction of seeing a small percentage increase become a noticeably stronger performance a few minutes later.
Keeping Your Hands Busy
One of the more interesting touches is the ability to manually collect coins dropped by defeated viruses. While your minions are busy dealing with the threat, you can intervene by moving your cursor across the battlefield to gather the currency they leave behind. It is a small mechanic, but it gives the player something meaningful to do between decisions.
Without this feature, Increbraintal could feel almost entirely passive at times. The coin collection adds just enough interaction to keep your attention engaged. You are still not directly controlling combat, but you have a reason to keep watching the action and responding to what is happening on screen.
It also fits the game’s overall personality. Increbraintal is not interested in turning its simple premise into something unnecessarily complicated. Instead, it keeps finding little ways to make the basic loop more satisfying. Collecting coins may not sound exciting on paper, yet in the context of an incremental game, every handful of currency feels like another step towards the next upgrade.
Cute Rather Than Creepy
Visually, Increbraintal adopts a distinctly cheerful approach to its biological setting. Viruses, defenders and other elements are presented through colourful cartoon artwork rather than anything remotely unsettling. That decision suits the game’s lighthearted character and ensures its brain-based setting feels playful rather than grotesque.
The interface is clean and easy to understand, which is particularly important for a game built around formations and upgrades. You can quickly see where units are positioned, how much currency you have collected and which parts of the Skill Tree are available. On the Nintendo Switch, that clarity is especially welcome, as the smaller screen can sometimes make strategy interfaces feel cramped.
The sound design follows the same philosophy. Rather than bombarding you with an enormous soundtrack or dramatic orchestral themes, the game relies on light music and simple effects to accompany combat and progression. Attacks have enough impact to make battles feel active, while the sounds associated with collecting currency provide those little bursts of feedback that incremental games depend on.
Built for Short Sessions
Perhaps the most appealing thing about Increbraintal is how easily it fits around the rest of your life. You do not need to set aside an entire evening to get something from it. A few minutes can be enough to complete some battles, gather resources and purchase an upgrade before putting it down again.
That makes it particularly well suited to the Nintendo Switch. It is the sort of game you can play while sitting comfortably on the sofa, during a short break, or when you simply want something uncomplicated to occupy your attention. There is no expectation that you need to master a sprawling campaign or remember dozens of systems every time you return.
Of course, that accessibility comes with a trade-off. Players looking for deep tactical combat, complex deck construction or a lengthy strategic campaign may find Increbraintal rather lightweight. The game offers enough variety to make its progression enjoyable, but it does not attempt to compete with the genre’s more substantial offerings.
A Little Strategy Goes a Long Way
What makes Increbraintal work is its restraint. It could have buried its straightforward concept beneath layers of unnecessary mechanics, but instead it concentrates on a handful of ideas and lets them work together. Formation, automatic combat, resource collection and permanent upgrades all feed naturally into one another.
The result is a game that feels immediately approachable while still giving you reasons to think about what you are doing. You may not agonise over every move, but there is satisfaction in discovering better formations and watching your defenders become increasingly capable. The Skill Tree provides a clear sense of progression, while the short battle structure keeps the experience moving forward.
It is also worth remembering that budget games do not necessarily need to offer hundreds of hours to justify their existence. Sometimes a game can simply provide a pleasant diversion and do that job well. Increbraintal belongs firmly in that category.
Final Thoughts
Increbraintal is a charming little strategy experiment that turns the unlikely setting of a human brain into the battlefield for an accessible incremental auto-battler. Its automatic combat will not satisfy players looking for constant hands-on control, and its relatively light mechanical depth means experienced strategy fans may eventually find themselves wanting more. Yet there is a genuine warmth to the experience that makes its simplicity surprisingly appealing.
The combination of formation-building and permanent upgrades gives the game enough strategic texture to keep you thinking, while the coin-collection mechanic provides a welcome touch of interaction during battles. More importantly, the progression loop feels rewarding without becoming demanding. You are always working towards something, whether that means unlocking another Skill Tree improvement or finding a formation that can carry you through the next wave.
For Nintendo Switch players in particular, Increbraintal offers a pleasant pick-up-and-play experience. It is cute, uncomplicated and refreshingly free of unnecessary fuss. It may not revolutionise the auto-battler genre, but it does not need to. Sometimes you just want to sit down, defend a brain from an army of viruses, watch your tiny minions do the dirty work and enjoy the satisfying feeling of becoming slightly more powerful with every run.
Increbraintal is a fun and accessible incremental auto-battler with a likeable premise, satisfying progression and enough formation strategy to keep its simple combat interesting. Its limited depth and short length prevent it from becoming an essential strategy experience, but as a casual distraction, it does exactly what it sets out to do.
