Did a few playthroughs, the game is looking great, tons of potential. Here is some things I'd personally fix/add.
Change the monster's FOV to include a little bit behind her. I found that you can actually just follow her and you won't get caught.
Assuming this is planned, but random map and monster spawn point generation.
Maybe a small tutorial level? It was a little weird getting in, as I didn't know what anything was.
You could add a *slight* static filter to the UI to make the game look a little more "vintage" and spooky, with options to disable for those not really looking for an actual game.
Specific game modes (collect x# of items, hide n' seek, whatever) for potential item rewards instead of money, or lowered money yields.
Thanks for your consideration, and I wish you luck!
