Level Design 3/5 : The places have good texturing , but few of props.
Lighting 2/5 : The lighting is not so many. I understand that this is a horror map, but just the flashlight alone can confuse the direction.
Sound and BGM : 3/5 : Only horror ambient noises, should add some horror musics.
Story 2/5 : Simple story, and why it's called Oh My God like previous maps?
Gameplay 3/5 : Playing make me scary, but it's ruined by un-make sense traps with no clue how it triggers.
Unique 3/5 : Spooky map, Make me beware for every step.
Conclusion: 2.5/5 but I will give 3/5
