It's so simple and so smart! It's a perfect example of small ruleset emerging into complex thing. The music transition hits hard - my eyes see cubes, but my brain panics and runs for its life in fear! It makes me feel vulnerable. It just works. The game design and balance of speed is perfect.
There are some bugs with killer and button not activating as expected, but it's not critical for a jam game.
Congrats on cool submission
