Okay so I tried this game and it's well polished and well presented. The only minor gripe I had is that I didn't even know what key to press to activate menu items. So I even had to fiddle to reach the help (but what really happened is I fiddled my way through guessing the controls, somehow).
I think you can get a pretty decent idea of what it does, and how it feels, by looking at the animated gifs : )
Of course it's worth a couple of bucks (like 1000000s of other nice indie games)
