THERE I FINALLY FINISHED ACT THREE
This map was mostly just an excuse to fit that awesome tree sprite from the DS+ pack in. This is where [you] and Onyx have your big, tender moment (although just HOW tender and what kind of tenderness, that's up to you). Then it starts snowing (which I learned that RPG Maker does all that for you, too, without additional scripting or coding, and why did I put off making games with this engine for so long). Then there's a big conflict that sets up the climax.
I also wrote out the ending because I got hit with inspiration on how to tie up some of the other loose ends, but I'm not spoiling that. ;-)
Tomorrow I start act four, which is going to start with [you] repairing Onyx's arm after his owner beat him so hard that she knocked his arm off. Surely, this will not be too melodramatic.
