Works with blender 4.5.6
But in blender 5.0.1 it more or less "works", but the tile set viewport used to choose tiles do not show up, making it impossible to use in blender 5.
Viewing post in Sprytile Forever v0.1.00 - A port of Sprytile to Blender 4.3
I already made some adjustments to make it work with blender 5. I've made a pull request in your repository. please, take a look
