Nice attempt at a mario platformer. The sprites were well made and the controls worked quite smoothly. My issues were that I couldn't really get a very good grasp of where I was going and it seems to be a very small window of jumping on enemies unless you double jump, I also didn't realise there was a double jump right away and spent a couple of minutes trying to jump up the first big wall, thinking that maybe the game was broken. Additionally running and jumping animations for the main character would be awesome.
