I've made new tileset for platformer games with 13 different variants that use different palettes and dithering. Each tileset contains 132 tiles in 64x64 or 32x32 PNG format - look at screenshots for hints how to combine them into interesting platforms and shapes.

these look quite solid! the green tiles are noticeably a teeny bit blurry, but I assume that’s just an itch thing

Thanks. You were right about the blurriness - when making the test level I forgot to set Inkscape to pixelated image rendering and it blurred the tiles - I updated them now in the thread. The tiles themselves are sharp. :)
