We almost started making game with the same mechanic but come up with a different idea after all :)
Mechanic itself feels nice and interesting but
- Clockwise and counter-clockwise images look almost the same and because of that it takes extra seconds to figure out what I want to do
- Game itself feels a bit slow, would be nice if it was a bit more realtime somehow (although, I realize it is not that easy to make and may be it’s just my clip culture)
