Amazing game, but I found a bug. I found the key in the painting before clearing the boxes out of the way for the door, so I cannot re-find it to unlock it. So, I'm effectively soft locked for that progression, whatever may be behind that door.
Thanks! I beat everything in the game, bought everything in the shop, and in all that time I didn't even notice I had a bag. Could be a me-issue, but I suppose a quick tutorial of UI elements wouldn't hurt for unobservant people like me.
