Well, it is bad, but the boring kind of bad, and the game being unfinished doesn't really help it.
-Gameplay is infinite from what I've seen and is extremely simple. Controls aren't bad once you find out which ones are.
-The art is the worst part (in a good way for the jam) with it looking indeed like something made quickly.
-No sound, therefore I cannot really rate that.
-Has nothing to do with the theme.
