You did a really good job capturing a PSX games look and feel. The sound design is good and atmospheric. I appreciate that you took into account falling and dying in the water. The interactions are simple and intuitive. Theres not really much else to say. Theres no game loop for a survival horror, as there aren't currently any run or hide mechanics. I dont know if its the type of game you hide from the enemy, where you fight them, or where you use the environment to slow them down/damage them.
I do look forward to what you do next though. :)
