Hi! I'm interested in this — a single-location PS2-style horror game is a great, achievable format for a first game/film tie-in, and I like the Psycho Inn inspiration.
A bit about me: I'm an indie game developer (4 titles shipped on Google Play under O2cool168), working primarily in Godot 4. Since you mentioned you're newer to game dev, happy to walk you through what's realistic for scope, timeline, and style once I know more.
A few things that'd help me give you a real answer: what's your budget range for this, roughly what timeline are you working toward (is it tied to the film's release?), and do you have a link to the short film or any reference material so I can get a feel for the tone you're going for?
Looking forward to hearing more!
