Ok I actually liked this one quite a bit, but it is really hamstrung by some technical issues and lack of clear instructions.
The most glaring technical issue as mentioned in another comment is that the door interact interface is impossible to close. While it's still possible to feed the door and defeat the monster with the screen there, it's incredibly annoying and makes the game far more difficult then it needs to be.
I also found the doors opening to be a bit too obstructive, pushing me out of the way or blocking my path. But in jams and first time 3D games I find that's a common issue and one I've done myself so it's understandable. Slightly annoying but definitely not a non-starter.
The lack of instruction also really drags down the game, I discovered the lock door by chance and only learned how to unlock it by accident. The door is kinda hidden despite being right next to the evil door, and with the instruction screen blocking most of the players view it's hard to see the locks even if you find the door.
Aside from those problems, I enjoyed the game. Running around the house and interacting with everything searching for food and keys was fun. It took me 2 tries to complete the game, as I only learned about the keys when I had a few seconds left in my first run.
I also really liked the sorta low-poly model with JPEG photo-texture aesthetic, I don't know why I just find it oddly endearing.
For a first venture into a 3D game I think this was pretty promising, if you fix the instruction screen bug and add some information telling the player how they can defeat the monster this game will be pretty solid.
Good work!
