I loved this game! Here's my video on it! Feel free to incorporate it into your games post if you would like!
Glad you enjoyed it! Thank you for featuring the game in a video. It was fun to watch. You're spot on about the door. We're writing up a small guide on how to get the "good ending." We'll be releasing it in a dev log post here. We may give it a few days though, just to see if anyone can figure it out first :)
