in these two scenes:
JNHenryFooled?
open front door and click

and ending ?JNDenouement?
pickup pickaxe and break wall then proceed forward

they sometimes, not always, and hard to reproduce
they play too fast as seen in VIDEOS attached

shortly i'll be providing two saves
fooled & end
(ha, i named the mp4 backwards. fooled = ending)

this may be a different issue, but the audio sync to the video is apparently broken
sometimes it syncs then possibly locks the next scene unable to progress

sometimes the video plays before audio sync
sometimes the audio plays before the video

noted i had no issue on "this playthrough" while playing the steam release (2026-02-15)
using Proton 10, opengl, scummvm 2026.1 windows .exe on linux

the two primary scenes noted in the OP played fine in this pass
