What's behind the door?

Hey! This was my first jam ever, and I hope you enjoy the game. It's pretty much what I could do with my current skills, but I really enjoyed participating in this game jam. It was my first project by myself (not following a course), so I'm proud of being able to deliver something. Some of the art was made by me as well.
