I just finished Sewer Call and really enjoyed it.
What impressed me the most was the atmosphere. The sound design, environmental design, and level layout constantly build psychological tension without relying only on jump scares.
I especially liked how the game immediately throws players into the experience instead of making them wait through a long introduction.
My only small criticism is that some sewer sections become visually repetitive, but overall this is one of the most interesting PS1-style indie horror games I've played recently.
I wrote a detailed review and design analysis here:

Thanks for creating such a memorable horror experience. Looking forward to your next project!
