Really simple game buta nice one for a first game! If you fix some bugs like sticky walls and ceilings (anyone who tried a platform has seen those), make the movements a bit less stiff (like with jus t a bit of momentum) and add some sound effects, it will become a proper little platform experience. Pointing those things out because, in my experience, they are the most rewarding dents to flat out, not requiring lot of efforts but giving you a most improved game, so keep up the good work
