This is not even a game.
So the idea was to make a music game, with randomly generated music and some fun mechanic to use it with.
So I wrote a beatbox generator and tried to have some monsters for a challenge. But the game just did not work out.
So what I ended up with is a toy that generates beatbox beats that you can listen to.

Hit Space to have a new beat. You can also walk around and kill the monsters, or be killed if you touch them from the side or jump on them while they beat.
