Thank you for playing and liking! Maybe one day this get fleshed out further, but we did the best we could within the time limits.
In regards to the bug you mentioned, yeah, there's a graphic bug that ranges from that happening to the image not being there at all. Someone made it known in the discord and I looked into it, but unfortunately can't update for the game jam version. The bug is partially also happening because the triggers for sending the player to the dungeon didn't autorun for that encounter. Probably something that got broken in the last 30 minutes in my mad rush to finish in time.
