Any wads like crapi?

If you haven't tried it, try it out: http://www.doomworld.com/idgames/index.php?id=14504

Skip to map 14 and 15, being bounced around like a pinball and white water rafting is so much fun. Not really concerned about free-roam, just crazy-fun stuff like that.

I think junko is in the same vein? It's by the same authors at least.

Marcaek is right, in fact Junko actually contains some of the more advanced parts of Crapi, although its multiple map-to-map paths and possible early ending means you might not see most of them.

Things actually very much like Crapi/Junko are pretty rare, or at least they've managed to elude me very well, anyway. Something that does spring to mind are the two Phocas Island WADs, with Phocas II probably being the most popular example of the style, although it deviates from DooM in terms of how combat plays out more than its predecessor or Crapi/Junko (although not so much that you won't recognize it, especially if you've ever played Hexen).

Edit: Oh, if it's the wacky crazy minigame aspect you were after, rather than the adventure game aspect, ever played Turbocharged Arcade?

Being spiked to death or playing battleship with a Cyb isn't fun. Rafting/tubing and being bounced around everywhere is fun.

Well, the sequel added a Doom variant of Breakout, which is actually kinda fun.

The ball is a rocket. The paddle is your face. You have to both hit the rocket to prevent losing a life, and grab a Megasphere between shots to prevent losing YOUR life.
