Finally finished it! That was a fun platformer. I really like the wall-cling mechanic; it completely changes how we look at platforming, and made the game in general a lot more forgiving. I enjoyed being able to just walk around most obstacles. The suit change mechanic was neat, too. I feel you got a lot out of simple mechanics.
I'm disappointed there isn't more to the story, though. There's this whole racism theme that's even ingrained in the mechanics, but it just goes completely ignored by the protagonist. What did the triangles do to piss off the hairies so much?
