Pardon me while I literally copy-paste my review of the first game.

It's childish humor thrown into an "unfair" old-school style platformer. Honestly it's gameplay is closer to Mega Man than anything else - Jump and Shoot, and plenty of insta-kills.
It's really good and fun for that kind of game - if you're into that sort of thing, definitely worth playing.

2 is basically more of the same as 1 - functionally they're very similar games. If you enjoyed 1, you'll like 2.
