The game concept is really cool and original ( going through a bunch of platforming challenges that are selected in a random order ) and actually matches the theme-
BUT, the game has only a handful of levels, the "Level" sign is glitched and doens't work ( along with some other bugs and oversights ), and the art ( while yes this is a game jam, you should have done more with less ) is eyestraining, with everything blending in with eachother, and the level design sometimes straigt up CHEATS YOU ( e.g. spawn and instantly die ).
Sorry if this comes across as jerky, it's actually a good concept and you did put in a lot of work... But, this game needs a lot of work for it's ideas to be fully realized.
