I got softlocked! Because the "seasons" reset whenever you leave an interior, I entered this house in the winter, without flippers. I exited, and ended up here. Even after dying, or exiting and reentering the game, i respawn here, and can't leave!!

Shoot! Thanks for reporting that bug! For now, if you open the save file (it’s just a text file in the folder where the executable is located) and mess with your world location variable then relaunch the game, it may move you somewhere where you aren’t stuck. I’d recommend changing the X coordinate by +\- 1.
