Fun times! Wasn't sure how to beat the dual pumpkin head and skeleton as the way was blocked once I jumped down into the pit. They were all cute looking but I got a little panicked anyways and ran away. I can't believe this was done in Godot! Awesome!

At the end of the hallway you'll see some roots grown in to the wall - you can climb up them to get to the next section. I should probably indicate you can go up that way with an arrow or something.
Update: I've posted a "Non Jam" update which uses particle-effects to indicate where climbing is possible, you can grab hold of the wall or roots and pull yourself up.
