Thanks for the feedback! You can complete the entire game with all the lights on as long as you don't flip the breaker, so I hope that helps with your dizziness. Also, maybe he lives on a farm which is how he can afford such large property :)
If you mean a highlight on interactable objects, I feel like that might take away slightly from the exploration aspect of the game, but I appreciate the idea! As for settings, it was simply cut for time. Sorry if the sensitivity ended up too high! I saw that on a handful of other games too.
Things do get crossed off the list if you check after doing things; it gets replaced after you've progressed to the next section. I was going to make it just accumulate but then I didn't have enough time to account for ever possibility, and it's still a bit buggy.
If you need help at all on your next playthrough, let me know!
