Get a quick idea of the game
The game is about bats descending from above,
And in order to multiply them, you have to solve the addition, millennium or division,
The more I get into math, the more I hit the bats.
But if you make a mistake in the operations, you lose.
So you have to be quick in math operations,
The faster you go, the more you advance in the game.
It is a fun game and also a trainer for your brain.
