Just watch. There are some small comments in the code if you want to check that out.
I used piskel for the leaf tiles. All other art is in the Bitmap or Vector editor. I'm not really experienced with pixel art or tiling. Based on/inspired by sevencrane's tutorial for wind-blown leaf shaders (in Unity), for his game Vapor Trails on itch.io (which is an excellent game, by the way). It's definitely not the same quality as his, but I think it's alright. https://7cr.co/blog/2021/01/10/leaves.html / https://sevencrane.itch.io/vapor-trails/devlog/215453/tutorial-wind-blown-leaves-shader Whirl/fisheye distortion inspired by various Scratchers. I should really learn a more efficient way to tile, but I don't code enough or have the time to do learn anything lol
