One of the most original games I have seen at this Game Jam. Or any for that matter. The name, the graphics and gameplay mechanics are all both fantastically thought up as well as theme-fitting.
My only gripe would be, it's a bit on the short side. So take that as a positive!
If you would add a whacky story and expand this to several themed groups, like the tribes in lemmings 2, of say 10 rooms each, this could really be a winner.
