1. Can the death warp from any% be used to skip about 10-15 seconds at the start of 100%?
2. Do you have to collect the map in 100%?
3. Is the priority time rta or igt?

I'll try to answer your questions the best I can:

1. If you mean death warping to the first save, that would save time in 100%. This brings up a big question though; can someone just death warp to the save before the final boss with all the items in the game, technically completing the game 100%?

2. Map is required for 100% for mobile. Rule of thumb, anything that is shown on the pause screen counts towards 100% (tools, keys, fruits, map).

3. According to the rules, igt for mobile and rta for web. It doesn't hurt to have rta for mobile though.

Maybe what you can do is set up two different categories 1 with the glitch and another category for the person who actually goes through and completes the game a hundred percent by getting everything.
