I think this plug-in is quite useful, and I hope that the MV version will be released to make the game performance more interesting.

Hello. RPG Maker Action Combat will only be available for MZ. It's like a game engine on its own so there are a lot of things for me to take care of, therefore it'd double the amount of work if I also make it usable in MV. Currently I prefer to make it the best for just MZ so I still have time left to do users support.
