Neat idea, it's fun to play, it looks great, and the audio fits in very well. This is like the opposite of other games I've seen with clones; instead of working with your clone, you're trying to avoid them, which makes for a difficult challenge. However, I wish there were some other changes to the medium and hard modes besides less time to get to the mushroom, maybe have 2 mushrooms to eat or add obstacles throughout the course? Overall, great work!
