Thank you for playing Yeti!
We were aware of the bug with the Centipede dude. A similar thing happens with one other monster you can encounter. We recognised this almost immediately after the submission window closed and alas we could not fix it. This was purely the result of forgetting to swap out a placeholder character sheet.
The blocked route in the cave section was not something i was aware of. can you confirm which cave you are referring to. Was it the one with the Square Rooms or the one with an abundance of blue mushrooms? I will look at this almost immediately as this could make the game unbeatable. FIXED THIS NOW. You were totally right. Thank you for pointing that out. 1 impassable tile placed blocked the route to the dungeon.
Thanks again for taking the time to play and leave feedback.
