We released a 2D platformer prototype name Legless Runaway. The unique thing with this game is that you cannot walk, because you play as a tree. Indeed, this is a very weird concept, and this is the reason why we would love to have feedback. We would not want to waste our time on an idea that nobody (except us) like.
