I wonder why there's no NG+ category of the game. That will be really interesting to see super-fast travel from the start to the Ending A/B/C in a couple of minutes. I guess the only problem is about working with saves. The solution is just to make a copy before pressing "NG+" button, so you don't have to recomplete the game for another NG+ save. Or, more practically, you can place a 100% completed NG save file in rules that must be loaded into the game before the run (AppData/Local/Ender Lilies/Saved/Save Games; the save file is GameSlot_X). So why not?
I am incredibly new here, but I've been wondering the same thing. The fast travel system would be beyond broken for a speedrun, and it would have a lot of routes non new game+ runs simply couldn't take, making it a fun mapping challenge. I know you made this post months ago, but it shared a similar sentiment to what I was already thinking. Also hi.
