Thank you so much, it makes me really happy you say that! I've been practicing pixel art in my spare time to become faster and more coherent with it in general. These game jams are a big help and show more progress every single time. These are some sources I used:
Creating a top-down tileset: https://www.sandromaglione.com/articles/how-to-create-a-pixel-art-tileset-comple...
Creating a color palette: https://www.youtube.com/watch?v=uUdMb8Bb2II
I used Aseprite for all of the art, which is honestly a wonderful investment if you want to do more pixel art. There are of course still a lot of things I'd love to improve, such as how I'm still using both 16x16 and 32x32 together, and we scale the assets in the engine afterwards on top of that as well.
