Could've been worse, he could've charged money for it.
Nope, not fun at all. The jumping control is stiff as hell. You have to time it just right. It's just annoying as all hell.
I have to say that despite the final battle with Jesus being very difficult, the ending with God killing Jesus and giving Simon a Pikachu made for very satisfying pay off. Also, the secret boss battle with the karate guy is also a bit hilarious, albeit very hard to figure out if you don't know what to do.
Ha! This game is funny.
