The game plays well but (since you are using unity you should apply a physics on the character that provents it from "frictioning" with the walls)
but the level design and overall gameplay is really good and i spent quick the time in the game but once again (the point at the beginning) is the reason i stopped playing because it would get stuck to walls
if you can polish this one up a bit i think you have a really good game in your hands a little golden gem
