Link to game (and more information) is here: https://studioignotus.itch.io/the-towers-of-knowledge

This is a 2D turn based game (like Pokémon, but without the catching), the twist is that to do any combat in this game you need to do math.

Currently only the beginner stage is available, but it has infinite level generation (so as long as you can solve the problems you can go further);

You can also download the game for free for both linux (mono & IL2CPP) and windows if you would like to play it locally on your computer.
