Regardless of what I do, when I play the sister's song on the piano, the "E" key, well, it "sticks", and it won't let me play the song, so I can't get to the basement.
I agree with asmodeu2 - it should have checkpoints. When you can SEE the exit and miss it, it's very frustrating to be forced to start the entire level over. It's a cute game, and a good idea. 3/5.
