good job
Interesting mix of the polarity idea and megaman. I think this supplements the 3 animations you created quite well. The game was easier than megaman, but still a challenge. Giving us 3 lives was suicide. 10-20 would be more reasonable, but I prefer 1/0. Infinite lives are a decent substitute for continues and would require little additional programming (a guess).
Interesting that none of the reviews I read had a spoiler for the cheats, which I thought would be helpful. The game told me the first cheat somehow, but I couldn't remember it after I died. Of course, the one thing that always pisses me off with these online games is the starting over from the very beginning after losing all of one's lives. I can imagine few things more frustrating. Even using the right click play thing (knew about, but didn't think about using until after reading the reviews) got tedious very quickly. In the end, I lost all patience and decided to do something else. Good game, and good implementation despite my grievances.
It is also interesting that some of your replies to the reviews are similar to my own writing style/mentality.
