The Lovely Tactics Hex project is a framework for development of tactical role-playing games (TRPG), built using the LÖVE2D engine. The main games used as inspiration for this project are Final Fantasy Tactics Advance (for GBA), Jeanne D’arc, and Trails in the Sky (both for PSP). The “Hex” in the name is because the battle grid is hexagonal. I plan, though, to adapt it to orthogonal and isometric grids someday.
Details of how to install and test this framework is in the project’s repository: https://github.com/GloamingCat/Lovely-Tactics-Hex.
All you need to do to start using it is download the newest demo (download links are available in the project’s repository mentioned above), and then follow the engine’s tutorials (available here) to create your own game.
