gee that's quite a game. the difficulty is a bit above my level, but the presentation - barring the lack of music - is immaculate. The art, the SFX, the diegetic room number and death count, character animations, all really good. I especially like the death -> respawn sequence. it's very quick but has a lot of stuff going on.
easy level 10, when I slide down out the bottom of the screen while holding right, I end up trapped in the wall at the top when I come back in.
the difficulty curve seems a bit all over the place. nightmare-hard levels followed by easy trivial ones followed by hard ones etc.
I like that it saves your place automatically. I had to quit and restart after the level 10 bug and it was nice to not be asked to beat the first bunch of levels again.
