Does art ending legitimately take 4 hours?

Unfortunately, as far as we know, there is no way to make the Art Ending take less than 4 hours without cheats/hacks.

do a run of 22/13 Endings and I'll add it Kappa

well if anything, 22 endings cause it doesn't auto reset after the ending

or we could add an "All Dialogue" category which takes god knows how long :P
