I think the idea is excellent, the music is "sound" but the pull-up mechanism works way too fast. I had to stop playin on the level which has spikes on the floor and on the ceiling....I felt like I did not have enough control to pull just the right amount.
That level should be removed or moved because it is a huge turn-off.
Also...when I hit ESC I have no level select so I have to do everything from the beginning? This is just not gonna fly.
