I played for 7 minutes and idk if there is an ending. But I have to be actual competent tester I’d suggest moving arm on top layer, so the brightness of window won’t imprint on it when you hover over it, and add some sort of mechanic to combat pre firing David (by tapping him before he even moved and moving back when he actually moves, you can just make option disappear after 5 seconds of not tapping them) and sitting in the dark for too long, cuz I just sat there with closed door and lights shut pre-firing David’s movement for full 7 minutes with no issues
