The game controls very well, and the popcorn physics are convincing and intuitive to interact with. There isn't much game here though, as there aren't win or lose states. It seems like a solid base on which to build a game where you had to use the popcorn physics to solve puzzles. I think the audio is somewhat adaptive, at least, the shaker sound which a new wave starts gave that impression; if so, that's a nice bit of polish!
