Great game! I like how cohesive it is. Good visuals, good audio, fun to play. I managed to get 26 medals on my first try. Seems like there's some nice variety of levels, I wonder if I saw them all. It certainly gets harder later on, is there actually an end to the game or is it as far as you can go?
The only one I couldn't figure out is the one where you run from the laser beam (it's one of the screenshot too). I tried to tap the button or hold it, didn't seem to work, is it a timed thing?
