Very very cool game! I like the concept and you executed it well.
I would have expected the king to be able to move diagonally, but with the fast-paced movement it kind of works without. I also feel the game is a little too RNG dependent, if you get three bishops spawned next to each other, they can cover most of the board.
The music fit very well, and the sound effects were nice.
Overall, I had a lot of fun playing the game! Good job 😃
