I just finished playing your game, and what stays with me the most is the way you've handled lighting. Each location has a distinctive lighting and color scheme which makes every one of them memorable in their own way. The way you managed to pull out those door transition was neat, sometimes when I see games doing this Resident Evil reference it can appear just a bit bland, but you made them look really good and fully part a the experience.
Low res audio was cool too and it sat the mood efficiently. Special mention to your ocean wave splash effect that i found really creative and gave a certain charm.
Overall a nice narrative experience, spiced up with well cooked cutscenes. Perhaps it was lacking a bit of some elements of tension most part of the game.
That's a big well done !
