It's impressive that you made a complete game with style, but I feel like the mechanic and level design of this one is a dud. The timing of the tumors makes it look like even the ones in the first level are impossible due to no clear visual indication of when the tile is safe to enter. On top of that, you've got puzzles that rely on the player being able to do non-puzzle actions perfectly across the entire lvel to work, which is not helped by combining movements that fit the music with actions that require several movements within one beat. I also think it was a bad idea to have levels spanning multiple screens without both the camera following the bus (so the player can see what's ahead) and the ability to look at the full level before moving (so the game isn't just trial and error). Still, everything else about the game is great. I left it going while typing this to keep the music on.
