This wasn't bad, I liked the atmosphere and that this game was quite creepy. I found all 3 diary entries, which i was proud of haha.
I did wish for a light source, as when i was walking around I did wish for a flashlight, as it was impossible to see things, probably why it took me longer to find the code. But I got there in the end and I enjoyed the concept of the game.
Keep up the good work! Here is the playthrough
