Dude, this is amazing! I had looked into doing an action battle system Zelda-like for RPG Paper Maker a few years ago but decided it was going to be too much work...
I am curious, will you be releasing the code / project files on GitHub or something? I'd love to take a look at the plugins you've written.
I may have to tackle this again knowing it can be done. I love the style of this game engine!
Thanks for sharing your progress!
