This will be a thread for future suggestions. New categories, rules, mods, etc. I'll start off in the first reply.

Your suggestions should have

Suggestion title (example: 100% category), and description (example: 100% has a different route with different risks)

Suggestion : All collectables category.

Description : much like 100%, all coins and gears have to be collected. But unlike 100%, you can abuse death and checkpoints. Also allows for more leniency towards death.
