I just released the full version of Space Numbers, a game about mental calculations, but in a deep space environment, to add some fun and complexity.

At low levels, it is suitable for young players to learn and train their addition/subtraction/multiplication/division tables.

But it can also be fun for older players, when it becomes more complex, with several operators at once, higher numbers, and lots of perturbations.

Because, while resolving mental calculations, you'll also have to deal with aliens, harvest blobs of Fluid, grab various bonuses, and work against the clock, so you'll need some concentration

This full version includes many built-in levels, but also custom levels, that the player can tweak precisely.

There is still a demo version, limited to few levels of different difficulties and 1 player.

Feel free to tell me what you think about it.
