Apologies about the drum hit at the start! Appreciate that is probably way too loud, especially on headphones. Cutting the first second out now and also adding a fade in for music track on the menu music to ease you in!
The tileset/isometric mismatch and the pixel grid fringing are both great calls. I am by no means an artist so this is a big help! I hadn't come across Unfake before, that looks super useful to clean up the existing assets and any new ones I generate.
I came across https://www.pixellab.ai/ today when I was researching unit sprite animation & tileset generation and think I may have to redo a lot of the graphics entirely, seems to be the most expensive part outside of the Claude Max plan..
Running through your suggestions with Claude now to get them implemented. Cheers!
