Alright there is some VERY obvious flaws about master chief. First of all he can stick to the sides and top of everything when he walks into it. Sometimes he "jumps" really fast when he jumps near the top of a "platform". Also if you use slant platforms and jump into the middle of two slanted (diagnal) platforms backwards you sometimes litterallu "jump" through the platforms. The game needs some serious collision fixing and I could help if you want. Im best at programming and platformers are my specialty. If not I will be glad to beta test.
