This is not a guide, but a warning. Don't waste your time trying for this. You may think you know what's in store if you go through the first few levels of "Masochist", or play a Free Play level with all sliders maxed out, but you don't. There's a reason it's called "Shenanigans!" - I think it's a joke by the developer on us, and not a very funny one.
The reason is simple: Level 319.
Some previous levels (like 310) are extremely tough (similar to a maxed-sliders Free Play level). But doing three 310s in a row would be trivial compared to level 319. Unlike the game's normally generated levels where the "path" involves running to the right at near full speed, 319 features the Wheelie hero bouncing unpredictably through the level, coming to a stop and accelerating, playing around on clouds, and just generally acting completely random. Naturally, the level is packed with obstacles such that the only way through is to match him precisely. The level's a minute long and features about 40 jumps. With a fair amount of effort, I've managed to survive the first *five*.
Perhaps with weeks of playing nothing but this level, somebody will manage it. I have my doubts; I don't think it's doable by a human.
EDIT: Fuzzy Gray Wolf filmed the AI playing through level 319 and put it on youtube. Thanks! I'm adding a link so you can see for yourself.
