A lot of positive to say, the game is really a masterpiece.
The level design is super great, i have never got lost, the only the thing i can say is the adaption to the mini-game early but when you understand where they are, the game can start.
A good writing of the story, well done
The ps1 graphics style with the fixed camera is really great, it adds a lot to the atmosphere, there's a lot of decoration, little details, the mini-games are simple to understand (even tho i don't like the wave one just because it's hard to match but it's not a critic, it's a skill issue on my side)
The music and audio have one single issue, the alarm should be varying differently, because the first time the alarm changed to prevent me i need to be quicker, i just thought an event happened somewhere. Otherwise, the alram doesn't annoyed me.
A lot of people complain about freeze, i played on the browser, i didn't had a single freeze.
So yeah great jobs, you have made a complete game with polish, with a complete lore, good job!
