I was short for me, and only got a few flinches because of jumpscare elements.
I also want to give you a tip - the footsteps are too loud and they are too fast-paced compared to your ingame speed.
It definetly got potential, but I had nothing to do once a certain scene played out (dont wanna spoil it on here), and nothing new happened afterwards. I played for about... not even five minutes.
The idea is really good. Try starting the player with something small, then build up from there. You definetly have a lot of space to scare.
I will definetly play again in the future to see what you made :)
