Really well polished visually! Love the retro platformer look and feel, as well as the bopping soundtrack. Gameplay is fun in bursts, though quickly gets a bit frustrating, especially when you have to jump from one end of the screen to another. Not going to expand on the time mechanics as it's already been mentioned so many times, but I think a countdown timer would make more sense, if anything. Anyway, good job with the project - it's something I could see perform well as a casual phone title. Keep it up!
