Hello sorry to hear that, most everyone have been able to figure it out and it's not too difficult. Go to TV on first floor, get key stuck in teddy bear on top of TV for second floor door, go to bathroom in way back on second floor grab another key hanging from a rope over a bathtub, Go to top floor, solve doll puzzle and so on. I know you don't wanna spoil it but perhaps check a video if this I wrote doesn't help you. I'm a bit confused how you are stuck if you just started playing.
You're welcome and appreciate the support, I haven't been doing these urbex games for a while but i recently posted about a new one so def look out for that https://x.com/AzaGameStudio/status/2058332890685899195
