Pengin :D
I did have the same problems the other comments said, the inputs sometimes not registering and the resolution making it that sometimes you can't see where to go were a bit annoying.
I also think the puzzles could have been a bit more interesting. The ice breaking on tiles on which you already walked on is a cool idea that definitely could've been used more (maybe make it so that if you go the wrong path you can't progress later because you cut off your own path?) as it is right now I never really had to think where to go next, it was always pretty clear.
But this idea definitely has legs. Playing a penguin that slides across the ice is very fun, solve the problems mentioned, add some sound effects and you got yourself a MASTAAPIECEE!!
