The plugin already supports handling action gameplay. For rogue‑like elements such as choosing upgrades and similar mechanics, you’ll need to use eventing, something I highly recommend practicing. Eventing is the key to creating any type of game you want, and RPG Maker Action Combat significantly enhances what you can achieve with events.
For tutorial, I don’t plan to create a full tutorial covering the development of an entire rogue‑like game, as that would take a very long long time. Not to mention, tutorials like this require me to create an entire game just to show you how it's done.
