This is looking really good and fun to play, but I'm going to be that guy and ask: do you plan on updating the battle UI (queue, stat placement/layout, etc) to not be something ripped straight from Octopath Traveler? Is this currently a placeholder while other tasks (arguably more important) are being implemented? Sorry if this sounds brash, but it was the first thing I noticed and now that's the impression I'm left with.
Thanks for asking this! The plugin I'm using for the battle system gives me limited options on how to customize it. I can edit the size of the windows, the colors of the gauges, icons of the shields, and adjust the positions of the characters. With the use of the Luna Engine, I was able to edit the menu of the battle system as well.
For the layout of the hp bars, I intend to keep them at the side to give space for the virtual buttons at the bottom for a future mobile port.
The turn queue at the top though I have very little control on how to edit it due to the nature of the plugin and the parameters it allows me to edit.
Thanks for asking this and I hope I answered your question!
