Luna engine MV is a plugin that basically allows you to have complete control over the menus and makes overhauling them a piece of cake, and many games like Lawmage Academy uses it to create their custom menu. The problem is, they only made the plugin for RPG MAKER MV, and i'm assuming it's not compatible with MZ. HUD maker ultra pro (the paid version) has the functionality to make buttons, but as far as i know it doesn't have keyboard support, and the free version doesn't have a menu screen, so i'm assuming the paid version doesn't as well. So, is there any way to either make luna engine MV compatible with MZ (legally, idk the terms of service), or a different plugin with almost the same depth that Luna MV has? im willing to go up to $60, which is the original plugins price.
