Hey, 

Consider uploading a win32 binary so it can be installed via itch.io client. I couldn't now first start playing at all. 

It's a nice take on the slender man idea. I liked the simple setting and idea. I agree that the knocking wears on you. At start I didn't bother, but longer you play it becomes very repetitive. Possibly at least change the volume level, pitch etc to make it sound different. Of course adding randomization of "you are being spotted" would work better and would probably add depth.

Great job on the game though!

ps. I got my ears destroyed by the "die" sound which is completely borken. 

its ok

You still have a day to fix some things, namely the sound compeletly breaking once you "die"
Secondly you have no reason to turn on the flashlight since you can still see without the flashlight
And thirdly OMG THE KNOCKING IS ANNOYING, there is too much knocking you should tone it down a bit in my opinion or make it actually related to having the flashlight on, cause i was playing with it off and it was just constant and i didnt feel any danger at all, it was just annoying.
4th The movement is very slidy

Eitherway props on working on this for the week especially solo, keep up the hard work.
