Really nice job. I think you could even do more with the "dad who is the escape room guy". Is the main character tired of his BS, or is he sort of fond of the puzzles, or are they really excited for dad's latest game? (How about mom, how does she feel?) Then there could even be some tension when the danger arises; is this part of the game or not?
Honestly the best thing about this game is Mrs. Burnwood. So often in horror games with a youthful protagonist, adults just don't behave like adults often do - in a protective or supportive manner. Nice to see a character of this sort.
Usually the "haunted PS1" vibe is meant to elicit feelings of dread - like you're playing a cursed game. I think the low fi aspect to it here could be explored a little more. Is this the memory of someone who played a lot of PS1 games? Etc.
Best wishes on what comes next!
