Hello,
Honnestly I don't see the point in complaining about a minigame, qualifying it stupid and ridiculous, then saying in the same post that you'e not good at minigames. Isn't it the answer to your question ? Maybe that's just not your thing, and won't ever be, it doesn't mean that the game is stupidly designed.
The rainbow tower was realy challenging to me, and it is for sure, but I know it's mainly because I need to practice. It's probably one of the best minigame I've ever seen in crazyparty, as it's globally a remix of all the maps/concepts we've seen in most of the minigames.
Best regard,
Simon
