Oh, another one of THOSE games. Yeah, I don't think someone who says "Jump exactly 23 time" or "My head's paining" is qualified to tell me I have an IQ of negative 400 something.
7777777.... Duke? DUKE? You think that's Duke Nukum? Oh that's sad. That's the frigging Doom guy! Everyone knows that! What the hell. And it's ID software, not 3d realms.
Greigh you have to jump 24 times. It's a stupid trolling game, remember that. Not even to the level of the "I wanna be the" series or cat mario. I think whoever made this was thinking that "go" meant jump again. So jump 23 times and go would mean jump 23 times and then jump a 24th time and land on the flag.
