I got soft locked, i went to open a door after a boss, i did not have a key, and it pushed my to the outher side of the door, and i can not decend.
In the demo version there are locked doors, weren't there?
I only encountered locked chests in the current version. And you have to drag your key from the backback onto the chest there.
There is even a key sword. But is only usable once and gets destroyed if you open a chest with it.
I did not have a key... I GLITCHED THROUGH THE DOOR
