I wanna add some points. 1, half of the current categories don't even have a run on them. 2. It takes a long time to master any% as my best is 17:25 on Xbox one after 4 or 5 hours of trying it for the first time (I have previous speedrunning experience so it's much easier). 3. Any% can take a while to complete and has much more money needed than a glass desert run which I've done in 9:35 and only need to buy the jetpack. 4. You only need 2 slime keys (1 at least but it's slower) 5. It doesn't require sleeping, and therefore less rng on food is going to happen.
Any% does take a while to master. The luck factor with money and fruit needed can be a struggle. I reckon an easier, yet still decently challenging category should be reaching the infamous glass desert. It is a shorter run, and it doesn't require too much luck in most areas. It still has some areas to master and potential for faster ways. I want to propose this category and If it is, the first run for it when I'm able to.
