Hey thanks! I've used quite a lot of assets from itch and unity asset store actually. I'll update the game to list and credit them, it's a big oversight.
Most textures are from ambientcg.com, that I index to remove lots of colors. Then I render in-game with a low rez and a LUT postprocess, it helps hiding all of the jank :D
It was quite interesting and easy to do, I'll probably make a devlog here about it.
