Welp, the game is actually preety fun, definitly it is the best "cubthon" game i ever played!!! I like the end level concept, where you start as *spoiler* then as *spoiler and then as *spoiler*. I definitly have some potencial! It is just my computer, or is therer no music? Anyway, Great Job!!!
Welp, definitly some more levels. You could try to add some post-process effects! Try to also change player speed at x a little bit(love it down a little). Also, sope particle-effects would b dope, becose as einstein once saiD: Duh, everything is bedder with particles! You could also good in off, add some mooving platforms, and something like infinite-mode, with some procedular generation(it actually is not tht hard). Mayby also some simpy plot, becose plot make every game bedder. That's for start. :)
