I haven't checked everything yet as I wanted to check the art first, and I think it's very creative for what's done for immobile Isabella. Makes me wonder how she'll look like after hitting the final inflated state (just hopefully she'll have puffy cheeks). I also think it's a good idea to make her overworld sprite and battle sprite to be green after hitting the final slimed state. Same goes for Jill as her overworld sprite while at the final slimed state is green, but not her battle sprite.
When I read "Added new battle sprites" and I saw Sporella, I thought it was already added in, but I second thought to myself, and realized it was her enemy/boss sprites that was added, and they look great! I do hope that all enemies and bosses get their sprites soon.
I do have a question, while I was doing the Sporella boss fight to see the new art, I berried her, then I questioned myself. If I miss used the berry items, how would I get more?
