I think this game has good potential. I tried to use the E, Space, or O key to jump. It doesn't seemed to do anything. I think you should use the space bar to jump instead of using the Up Arrow Key. Also, I seemed to won something I don't realized what's going on. I was trying out the space bar after getting so much deaths in the stage and somehow it took me to the Win Screen with getting all the golds. I don't know if this is a bug or not?
