Just played it, Her's a list on what you can change:
1: Make it so stickies fall of the glas (on all levels). Also, you do see other glass walls through the glass. And you dont see the bright white line from the wrong side, kinda weird. (Same for the other levels.)
2,3,4,5: Fine.
6: You can sticky the dark blue ceiling, but not the dark blue block. Suddenly you can't sticky the light blue wall anymore, they fall off.
7: Here you can sticky the light blue wall, but there is func nogrenade (is that how it's called?)
8: Again, first you have to pogo on the first dark blue platform, but then on the next, you stickies suddenly slide over the dark blue part. It's really inconsistent in the whole map.
9: On the dark blue ceiling, there is a small edge, gotta allign it.
10: Left light blua wall have nogrenade, at rest of the light blue the stickies fall off?
?? For some reason you can wallpogo on the right white line?
?
11: Fine, might want to remove the regen and just give it on the beginning of the jump.
12: Just did it with a double sticky.
13: Remove the first two platfroms, they are useless. There is a gap between the ceiling and the white wall. You can stand on the white wall.
14, 15: Fine.
Cap: No skybox, so in the water shit glitches out.
Just some quick stuff I saw.
