You have a unique and atmospheric artstyle with realistic textures, lowpoly terrain and cartoonish outlines . I don't know how they work together so well, but you have pulled it off. Object outlines make the dark cave corridors possible to traverse while the more realistic graphics make the game more immersive. The underwater blur, missing checkpoint system and the long unskippable intro scene make it really unappealing to go diving though. I found a bug that multiple tapes can be played simultaneously, but the voice acting itself is excellent. Awesome work!
