I guess it is kind of bold to submit a 2 player game to such a small gamejam, so you have earned my respect.
I actually found someone to play with and it was great fun!
At first I didn't understand what to do, but after realizing how this game works, it was really fun!
I guess if only the slime currently under the mouse would be destroyed, the game would be way more challenging and you couldn't just spam all the inputs.
But it's still amazingly satisfying to see all the enemies explode into colourful particles.
Good job!
