I really liked the PSX-era visual style. It gave the game a strong retro atmosphere right away.
One thing that bothered me a little was the camera movement while walking. The bobbing felt stronger than I expected, and it gave me a bit of motion sickness after a while.
The moment when the scene suddenly got darker and the huge Dune-like creature appeared was really fun, though. I think the game did a great job making that monster feel genuinely massive and intimidating.
Overall, that was probably the most memorable moment for me.
