how'd you open the door to the puzzle room? also if anything it'd be low%
edit: the only way i've been able to replicate it (holding A) is if I already opened it normally then locked it again.
it is necessary not to hold, but to press many times, and then you can go
like, just in that room, or throughout the run before? I sat there for a while doing 8hz mashing and nothing happened.
just try to press a lot of times and at the same time walk in the door and be sure to press the "play again" button after the first passage. By the way moderators in this game are alive?
i'll have to investigate it more at some point after we get the mod situation fixed up, including if it needs a different category implementation (if it doesn't work the first time through, it'd basically be a NG+ category). Though on the topic of low%, I'm not super convinced that the gameplay is different enough to warrant a split category. It's basically the same but more careful + slower.
