THESE ARE GREAT!!! Thanks for redoing them in the arcade palette.
btw @shakao and I recently made a tool for making sprite packs easier in arcade. You can check it out here:
If you press the import button in the top right, you can import all of the sprites from an existing project (via share link). Then you can use the export button (next to import) to generate a project that can be published as an extension for people to add to their projects.
