Well, I just figured out how to clip into walls very easily by moving the camera off screen when the guy is next to the wall causing the wrap around to move them off the map and when they are low you move in the other direction causing them to teleport into the wall. As for the game; it's a really cool idea, but this isn't something you should attempt as a first game, I'd say to save stuff like this for when you're more experienced as they come out as something that has a good idea and good game (not saying the game is bad, I'm saying the game shows a lot of the main stuff beginners don't understand)
