I love how Abby looks when she gets excited about something! (Though for a moment I thought she had four arms in the introduction.)
I also like that each interactable has two different responses to being clicked on, an introduction and then a followup. It would also be nice if they had a third for when the key has been discovered, but there's only so much time when it comes to making a jam game. :)
I thought for sure the key was going to end up being outside the door, still in the lock. I still have a long way to go as a key detective.
