This game is awesome and very satisfying with the sounds of the raindrops!
One small note: if you place your character on the far left of the screen, you will never get touched and can just let the game create randomized music forever. Not sure if it's a bug or a feature.
Edit: I didn't realize the point of the game was to get to the right side of the screen. I thought it was just to avoid the raindrops! Maybe these can be 2 different modes? Perhaps a simple intro graphic or even an arrow pointing to the door giving some indication of the goal would be helpful. Either way, great game!
