I'm really liking this game. Lovely graphics and concept.
I think a "chill mode" (no gravity) would be a nice feature to incorporate.
While I think the boxed parts are a cool idea, I find the game difficult enough without them.
I have a bit of trouble quickly reading the orientation of the eye blocks for some reason. It should be obvious, but I find myself making mistakes with them, and wishing for a slightly more blatant indication of orientation. That might just be a me problem. My girlfriend has trouble with the legs and not the eyes, so who knows.
Anyway, I look forward to future versions : )
