Guys, I would gladly burn $3 at your request, it's nothing. Spending it on Canabalt wouldn't upset me as much as some of the complainers here even if I abolsutely hated the game.
Tough call, they're both really similar games. In both games, the main character moves mostly towards the right of the screen in some manner. Coincidence??? Even tougher: I heard somewhere that Hook Champ is adding a Canabalt level as its third update. Confusing things even more: There's a rumor floating around that Canabalt is going to add a grappling hook and customizable hats as its third update. Also I guess ceilings to attach the grappling hook to. You could get both for five dollars right now.
