I could certainly add per-character high-scores. When you fall off the first time, it would submit your score to that character's scoreboard, and then you could re-spawn and go for an overall high-score. Does that sound good?
I have played through all the levels that are currently available, gotten all the achievements, and have bought the right to refer to the power cells as batteries. After having done all of that, I only have one minor complaint. I feel that the means to get power cells are meager, and slow. If it is at all possible, could there be some kind of translation of meters ran into power cells? Like gaining one every 50 meters or so. If not, thats okay. It's not even all the important.
