My second contribution to the One Hour Gamejam which, as you guessed, about making a game in 1 hour. Wish I had more time for some levels, those here are a bit random and the game could get a bit more interesting with well thought timings. Not enough time neither for a playable random generation. Well, you ain't do much in 1 hour. But this one has sounds, yay!

Edit: corrected a bug crashing the game when accessing last level.
