Nice idea! Implementation is good, graphics and colors are interesting, there's atmosphere. Mechanics seem too complicated, I only used "pause" ability, aside from one slow elevator that required "fast forward". Maybe you could focus more on one ability and polish it better, for now many abilities only overload player's head with difficult controls. Or make it more puzzley, with levels that require every ability and combinations. Difficulty is not super high, but rather annoying. Player has to do lots of tries, so you better do respawn instant, without needing to hold. If you ever do a "hold" button, make sure to add visible and audible cue to it, like a bar or a timer. Overall I enjoyed the game, good job!
