I really like the retro shader, the game looks awesome and it has a great atmosphere, music is fantastic as well.
The scaling doesn't seem to work for me, it's probably only correct in 1920x1080, but that's not a big deal.
I really struggled to find the key because
1) i kept trying to get into the watchtower (although that's for sure my bad)
2) big antler guy was way too fast for me to properly search the area, even when I lured him away a bit
Also the jumpscare was a bit loud after the first time. Maybe have it be at lower volume later?
But that's all just areas for improvement, it's a really solid jam game as is and you can be proud of yourselves!
