I like the art/color switch to 4 colors being a plot point, which was a very cute way to use the restriction. I love how ridiculous the whole thing is.
I don't like the Boss fight creator's note because it comes off more down-on-yourself than feeling like self-deprecating humor. You made a game that works in your first Game Jam... There's some animation. Platforming that more or less works, and a guy with a clock for a head.
In the end, it's a bizarre game that makes me question WTF did I just play. In a good way.
