8/10 - very cool little game. It has some charm into it and overall i'ts pretty well made. I like the way you designed the "enemy", i loved that he changes appearance, he is an enemy that gives chills when you look at.
The gameplay is very smooth but i'd prefer more FOV maybe keeping the 4:3 style but a fow this low for not running was a little bit to much.
Also i like the jumpscare, simple but on point.
For your first game is a great start! I can't give it more than 8 cause is too short, i'd like to see a version of this or something else from you with a well written and "medium long" story. (/'v')/
