Controls suck, but it's a great idea. Also, you can just push forward to skip a level. I like the ending screen, so 3/5. You should DEFINITELY consider revamping the controls entirely. Climbing walls is next to impossible until you can get a rythmn going, but then one mistake and you're back to the bottom...
The major problem is that your square can go off screen FOREVER. I went up, then accidentally over to the left and haven't found it since. Maybe make either a boundary or make it so that if you go left off screen, you will come out on the right.
