Besides sales I think either Archetype or where's my my water, or maybe kingdom rush. Something like that.
Hey now...you can't complain about lack of developer support, can you? I used to play it quite a bit, though I don't recall what I actually "did". It was certainly original, and came out pretty early in the appstore's life.? Reminds me of an old Windows 3.1 or DOS (can't remember) screensaver/toy...I've forgotten the name, maybe Castaway. A dude stuck on an island would go about his business, doing funny stuff...it was entertainment at the time! That makes me wonder...didn't a port of the old C-64 "game" Little Computer People exist on the AppStore at some point in time? If not, it should.
