If you fall into this screen from above, it seems to soft-lock. You fall down the right hand side, and just disappear. Exactly how I fall down there, I'm not sure, but I've managed it both times I've played. I think I might have fallen from the screen one up and right, but don't quote me on that - I was trying to dodge the monster both times, and fell. I can attempt to reproduce again on video if you need.
Hello! Thank you for pointing this out. This is a map data generation oversight that somehow didn't come up during our play testing last week. Unfortunately, I don't think I am allowed to fix it until the jam voting period is over. For now, this can be avoided by not holding the right input if you fall down this particular gap:

What can I say? I'm very "skilled" at accidentally finding bugs 😂😉
Thanks for the workaround, I'll give it another shot, and try very hard to not hold right if I panic and run out of the adjacent room and fall 😅

Hey, I did see your other comment before you deleted it, just didn't have a chance to reply the other day. Pinged you on Discord (assuming I remembered the username properly).
