Thank you for playing! The demo version of the game is the backstory of the main game, so you have a lot of questions about why and where the logic is)) In the full version of the game, all questions will be answered.
The demo starts a few hours before the events of the main game. You will understand what all these actions with keys and door bolts were for)
P.S The Friday 13 font is a reference to the immortal classic. I try to perform the game in the spirit of the 80-90's.
