This game is fun and the art is nice, but the game loses a bunch of points for having not nearly enough checkpoints, and seemingly having one of the bosses (the one on the bridge with the swinging balls) be seemingly completely impossible. I don't know if I'm supposed to be able to see the boss or what, but I can't, and I get captured randomly. I can't hit the boss or the stage hazards. As far as I'm aware, this is impossible to beat in it's current state. Maybe the downloadable version doesn't have these problems, but the browser version is what 99% of people are going to play.
