Spoiler Warning!!!!!
Just to explain what I mean, I've marked in red where the mysterious hitboxes seem to be. I can't move there, place boxes or shoot, so I'm guessing a wall object accidentally got placed there. Not a big deal though. This was an awesome game, and and absolute joy to play through.
yep, sadly knew about this bug; while trying to fix a weird audio glitch with the web version (which turns out, godot's 4.3 web exports are actually quite broken) I accidentally painted collisions over there and only noticed too late to fix it.
I'm super impressed you were able to get there thpugh; I was wondering if anybody would actually ever find our about the final bits.
