Thank you very much for playing the game! I greatly appreciate it! I noticed the issues with the pickups able to fall into the walls of the cabin, but, sadly I noticed it too late to do anything about it before jam.
There is an end game. You need only survive for 3 full day cycles, then Santa will land behind the cabin. If you interact with Santa, you win the game :)
Good luck if you attempt another run, and, either way, thank you again for playing!!
