The main one I have is GTS, which is short for Game Time Survival. There would be 2 subcategories for this category: Notebooks & No Notebooks.

For Endless GTS Notebooks, the rules are to survive for as long as possible. Using notebooks to slow Baldi down is allowed, but you must get a perfect score on the first notebook for a valid run. Timer starts after regaining control on the second notebook, pauses every time you begin collecting a notebook, resumes after collecting said notebook, and stops when Baldi catches you.

This mode would be a lot easier to accomplish due to the numerous slow downs in the early game. A person who collects notebooks fast enough can keep Baldi at a solid 2.5 seconds per movement up to and including the 17th notebook. Timing, however, would be difficult to accomplish.

For Endless GTS No Notebooks, the rules are to survive Baldi for as long as possible without collecting any notebooks other than the first two. You must get a perfect score on the first notebook for a valid run. Timer starts when you regain control after collecting the second notebook and stops when Baldi catches you.

This category would be the harder of the two for two reasons: 1) Baldi starts at 2 seconds per movement after collecting the second notebook and 2) there is nothing to stop him from inclining infinitely on a slowly increasing acceleration rate. I can estimate times in this category to be no longer than 7 minutes (8 minutes if RNG can provide).
