Like bob said, this appears to be an issue related with IE. I'm going to see if there's a way to fix this issue for IE, but in the mean time firefox or google chrome should work.
Hey guys! If you encounter any issues with the game, be it graphics, gameplay, or other, let me know! If I can reasonably fix it, it might just be fixed!
Despite the high difficulty from "physics-based" platforming (sometimes you can't jump off something you normally can), it was still pretty fun. Keep it up!
