So far so good on the layout and the tileset! It still needs work but I'll hopefully have that all figured out soon-ish. The hardest part is going to be the tree because I really, really wanna use that tree.
Decided to try a bit of a different project--one that uses very few external scripts and maintains a 'retro' feel, with all of the editing done by modifying the in-engine scripts. So far I've managed to get the menus to look the way I want; since there's no combat there's no need to worry about that stuff.
