I fixed it! the dalek was part black, the color for walls, so I made it a door. The character was too big to fit, so I shrunk it. I thought there might be a problem with the original sprite, which is why you are now a small version of the guy from platformer. Finnally, some later levels were blank with portals, so I removed the portals and wrote you win at the end. Later, I might add more levels.
