Hi! First off, I'm glad you enjoyed the game. The game was not only inspired by Edith Finch but also Being John Malkovich, with the idea of going through a door and possessing someone. The protagonist's girlfriend was thus possessed and that's why he went to the mansion.
The minigames were hard to balance as we had to get the story across. Some of them already have an abridged version of the original script. It was hard to manage, and some of the minigames came from technical/time constraints.
And regarding looking at the floor, well I don't think I actually ever tried it. We used a premade First Person Controller, with some slight modifications. The default clamp is probably too small to allow showing completely down.
Still, thank you for the feedback, and we're glad you liked the game and took the time to write a comment.
