Not bad at all, for your first game, this is well made.
I liked the overall atmosphere in this. Definitely reminded me of "Slender Man" with the minimalistic look. I think the game can be massively improved. I would suggest adding the notes, explaining the lore or the location the character is in. Add more ambience, subtle sound effects, more spooky sequences and definitely an objective list, because the player should know what they are after.
Best of luck with your future projects! And don't listen to those, who have nothing but negative things to say, trust me, they waste your time. Cheers!
