I really enjoy the overall concept of the game. Well executed, all around.
I am absolutely awful at this game (no rhythm andrew), but I am sure than anyone who has a natural sense of rhythm is going to have an absolute blast with it. Though simple on the surface, the combination of the trash-collection-mechanic, and the need to press the space-bar to the beat of the music, adds some appreciable depth to the gameplay.
Beautiful art. Wonderfully done, given the short timeframe of the game jam. The music is nice as well (got to love those chill beats).
This game deserves a spot in the top 20, for sure, given its sheer quality.
