Good job. for a first game, it is not bad at all!
Here are some things that I want you to improve for your next game:
-A pause menu and a proper main menu
-Better AI
-Lore or at least a simple explanation
-More horror elements and less cheap scares
-A controls menu instead of showing the controls on the screen at all time
I would love to see you one day, release an extremely popular horror title!
Good luck friend.
