Okay, my first review. It is a good first try. A fun, 4 world fan made demo of New Super Mario brothers, although not the best Mario fangame made. I really found it difficult at times, and even frustrating. The main thing I am concerned about is the room speed. The speed of something should be controlled in the object. Half the game's levels were too fast. You need to change that to normal speed, and when you have that debug program, the creator of the game can decide how fast it goes.
