That was a fun little level. The backtracking for the blue key was a bit annoying but saying that, most of the time I found that once you'd completed an obstacle once, there wasn't much trouble completing it a second time, so it wasn't bat.
I didn't find the text a problem, myself. I'm not sure I would have twigged to the leave-wall-while-climbing thing without it.
All in all, pretty good. I loved the drum solo those first blue bouncers were tapping out
I kept hanging around in that screen to listen to it.
