the main issue with it is the repetitive use of the rock tile - this makes the screen really noisy and also doesn’t draw your eye to elements like the player or gems and such. i reccomend only tiling areas which border the empty space
a great example is with @ADM_F’s upcoming game Kentonia Isles!
a great thing to do is to remove orphan pixels and try to cluster them into more purposeful shading to reduce the noisiness of the tileset
- orphan pixels are isolated pixels not connected to anything
defo have a read of this post by slynryd, it’s amazing
okok finally this for smooth tiling:
