I say yes to that, I'm curious as to how much time can be shaved off of each level.
Timer starts when selecting level, timer ends at entering Level door for standard stages, Final Hit for bosses, or "Vision Clear" for hoverboard and autoscroller levels. Video is required
At least that would be my idea of how it can be done.
Edit: Speaking of which, could you please add a 100% full category as well? "Required to start from New File. Timing starts on file select. Timing ends with final hit on 'All Visions Clear' splash screen. Video is required with submission."
A 100% catagory could be put on the IL leaderboards as well, requiering the collection of all moonstones in a level.
If you're learning this game, I'd suggest joining the Discord server (linked above), as it's more active than here and contain lots of information hardly accessible elsewhere.
