Ah, and now I'm getting an "exception thrown" error. hopefully this helps!
(2nd image comes first but itch.io won't let me rearrange them)
if I were to guess, it might be related to 4k monitor full screen that the engine can't handle.
ah, nice catch. no 4k monitor here (just good ol' 1920x1080) so maybe a problem with setting the wrong resolution too?
I think it might be a limitation of the game engine (AGS).
