So I've been wanting to completely redo this level basically since after I finished Plateau Pumps because I actually don't like it very much. Hell, Togepuku aren't even Porcupuffer (They're the spiky cheep cheep guys.) I've been encouraged to, and don't think it'll take too long since I already have an idea in mind.
Basically, instead of focusing on regular porcupuffer, I'm going to have the entire level focus on the jumping puffer, since he's more interesting anyways. Maybe I'd like to see him redone a bit but honestly I think we're too far gone at this point for anything ASM related.
I'd also like to change up the graphics in the level a bit but... Well, I don't know what the deal is with Map16 space at this point. Nor do I even remember what I had reserved in the first place. I'd be replacing ExGFX slots I already used, but I'm not sure about actually adding new tiles and such.
Basically, submit your changes as a pull request to the repo. Since only one person is working at a time, it's pretty easy to handle as long as you don't remove anything that any other levels are using. For map16: Make any changes you want and export each page (the entire page) that you change into map16/page#.map16 and we can easily merge it into the base ROM.
