Loving this game, would donate if my finances weren't crap and I didn't have to be a responsible adult.
My only issue so far is making the beast take a humanoid form. Before it had a Lovecraft "fear of the unknown" horror to it where we never see what it looks like but eyes, teeth and tentacles. Like if we ever saw more then what was always hidden, the MC would lose thier mind. It lost a lot of that for me when it started taking a more familiar shape.
But if that's the ONLY thing I can think of worth pointing out after 2 years, then you're doing a good job
