PoleRiders is a flash game, and the only way to really understand it is to play it. It is better with two people, and playing alone is far less interesting. Now that I have your attention, PoleRiders takes the idea of pole vaulting and adds a slightly bizarre twist. Instead of trying to vault over a horizontal pole, the object is to use the vaulting pole to kick a ball suspended in midair into an opponents goal. This is the latest in a series of games by Dr. Bennett Foddy who also made QWOP and GIRP.
Dr. Foddy's games are unique to say the least, and worth checking out. Despite his latest game's name, all of them are safe for work and most only require one player. The best part is that all are free, but the good Dr. Foddy isn't going to turn down money and most can also be purchased, so if you like his work go give him a few dollars. Or just enjoy some free flash game goodness.
