I found an exploit in moving platforms that will allow for scavenger hunt type levels. Dueling puzzles is a level where you have to beat three legs and at the end of each one you have to activate a piece that will carry you part way to the finish. You have to beat all three before you can get there. It's mirrored with the same three puzzles on each side, the design is for multiplayer. You can see which puzzles your opponent has beaten from the main checkpoint so that will ratchet up the tension. I'm in the process of uploading all the two puzzle variants, let me know what you think!

Edit: You can't actually see which ones they have beaten due to moving platforms not being synced for all players. You can only see the ones you have activated. You can still beat it with teamwork if you hold onto the back of someone else while they ride one of the ones they have activated.
