Not sure if I'm a big fan of typical streamer-rage level design, where you fall and must start (almost) from the beginning. I feel like the controls are not as responsive (especially in the air and on the jump pads) to excuse this type of level design.
Also, I guess that player has less control when Zzzz particles are on screen? I absolutely didn't get and forgot about that mechanic, so it could be that it's just skill issue on my part D:
Overall, for something made in half a day - amazing stuff! And as others said - it has some potential for more levels, more hazards etc etc :D
