Interesting premise with good storytelling, although the game does need some adjustments here and there.
Visually the game looks great. I loved the detail with the textures and how they were dissolving into each other, sort of retro old school effect. In addition to that, my favorite thing about this was the "blacked out" face on the corpse and on the angel, which added a little depth to the creepiness.
There were some interaction issues, like I was not able to pick up the trash couple of times while pressing "E". The translation was also a bit off, that can be fixed and the ending was a mystery for sure. Maybe adding some more information about the killer could improve the character development.
Otherwise, this was a solid experience. Best of luck with the future games. Cheers!
