Many levels in JUMP are just unsuitable for individual level running. Other levels are boring. Here is a list of the levels that, in my opinion, are more fun to run. If anybody has any suggestions, I might add it to this list or give a rant explaining why the suggested level is bad. You can also suggest me to remove a level from this list.

Here goes:

Mushroom Ledge Secret + Filtered Chuckleton Plains Normal + Filtered Bastion in Blue Secret+ Filtered + No Switches Baseball Mountain Disco Dance Party Chains of Atrophy Normal + Filtered Gourmet Hindrance + Switches / No Switches Disarray Pixel Perfect + Filtered Pipes in Literally... + Powerups Land of the Jolly Tan + Powerups Effortland + Powerups Euphoric Mushroom Backyard Roy + Powerups + No Switches Blockomancy + Powerups Spring Green Spelunking + Powerups Tunnel of the Living Rock + Filtered Fortress of Koumei's Trap Rapture of the Deep Normal Peek-A-Boo Secret + Powerups Siberian Precipice + Normal + Powerups + No Switches Peaks of Revolution + Powerups Glacier Soup + Powerups + No Switches Cool Kickin + Powerups + Normal / Secret Switch's Yellow, Yo Efficient Heat System + Powerups Melt a Meat Locker + Filtered + Switches Aquiferic Pressure Normal (Kappa) Under Construction + Powerups + DC's Boiling... + Powerups + Switches + DC's Crumbling...

As you can see, I tend to stray away from annoying levels or mostly autoscroll levels. I might remove a few for the sake of "less is more", but that's all for the time being.

OK, Nathan mentioned that he's getting computer parts. So, expect guides soon (either on nathanisbored's channel or on nathanisbread)

For 125 or Shattered Dreams, I would like to note the levels that have dragon coins that are either difficult to get or too time-consuming.

Sproingty: It's only like an extra minute, and even less if you steal a Yoshi from Salty Roasted Peanuts and start flying. Salty Roasted Peanuts: An extra minute max. Pipes in Literally Everyone's Business: Also an extra minute or two Roy: The fifth dragon coin is hard. And it's right at the end. Aquiferic Pressure: You can skip the entire first section with flight shenanigans. Efficient Heat System: About two extra minutes I think Perilous Pier (DEFINITELY) Swim with the Stars: An extra minute The Cave of Layer2: There is a dragon coin at the very end of the waiting room... Rope is Nightmare: An extra minute or two Manky Bridge (DEFINITELY) Ludwig's: There's this one dragon coin that you'll probably have to die for; not that much time lost though Rock Climbing Rush (DEFINITELY) Root of Yggdrasil Chains of Atrophy: The last dragon coin can be tricky. Disarray: You can skip a ton of this level if you don't get dragon coins. (DEFINITELY)
