This game is different from most of the games in this jam or any jam. I really love the graphic and the story, and obviously, there is a big story behind it, I'm looking forward to seeing it.
Some suggestions:
1. I think the sound is still worth improving. A piece of good background music and some sound effect would add more to the atmosphere.
2. Maybe add more animated items. I think it might be a time limit reason, but I really like the grass at the front door. maybe something randomly moves, a shadow, or a water drop, might add some flavor in the game.
All in all, I really like this game. Followed you and want to see a full version of it!
