Very funny game, it's always nice to play the kind of games that are based on such brutal realism. It's of course very Pac-Man -like, although starts even simpler, since you only have one opponent. On the other hand, it becomes harder soon as you get multiple opponents, since the only way to deal with the opponents (other than running away) is to hide in the bathroom. The changing level design also always brings a new challenge, since you have to learn new routes. Speaking of the resolution issue, a moving camera would also affect the difficulty, unless there was a map. I have worked with iFrame, but for now I just don't remember enough of the properties to be of any meaningful help.
