I really love how this shader is faithful to the vanilla Minecraft aesthetics as it's exactly what I’ve been looking for. That said, I think a few additional settings could make it even better.

Specifically, it would be great to have optional bloom and ambient occlusion effects. These would allow for a more customization while keeping the base shader lightweight. I think these features would be amazing alongside the pixelated shadows.

Additionally, I think the underwater fog could be tweaked. Currently, water looks clear from above but becomes overly foggy once the player is submerged. A slider or toggle for underwater fog opacity would help create a smoother transition.

Thank you for considering these ideas, and keep up the great work :)

Bloom and ambient occlusion are heavier than you'd think and I'm probably never adding it. Underwater graphics is something I might improve one day, but it's so rare in gameplay that it's not really worth it.
