Flare (Free Libre Action Roleplaying Engine) is a simple game engine built to handle a very specific kind of game: single-player 2D action RPGs. Flare is not a reimplementation of an existing game or engine. It is a tribute to and exploration of the action RPG genre.

Rather than building a very abstract, robust game engine, the goal of this project is to build several real games and harvest an engine from the common, reusable code.

Flare uses simple file formats (INI style config files) for most of the game data, allowing anyone to easily modify game contents. Open formats are preferred (png, ogg). The game code is C++.

Originally the first game to be developed using this engine was part of this repository. As the engine became mature, the game content was moved to an extra repository and is now called flare-game. (happened around sept. 2012)

The following links are specific to the engine

Games made with flare

  • flare-game A medival fantasy game. In the first days of the engine this game influenced most design decisions a lot. The art is 3d rendered 64x32 px isometric perspective.
  • polymorphable A game made for "The Liberated Pixel cup", which was a competition about game art and making a game thereof. The pixel art is 32x32 orthogonal perspective featuring a medival setting. The development has finished.
  • concordia Another game using the art created during "The liberated pixel cup". While this started without stress regarding the timeline for the pixel cup, this story is more thought through and the content is more organized.

Building from Source

Please see the INSTALL.engine file for instructions.


Settings are stored in one of these places:


Here you can enable fullscreen, change the game resolution, enable mouse-move, and change keybindings. The settings files are created the first time you run Flare.

Save Files

Save files are stored in one of these places:


If permissions are correct, the game is automatically saved when you exit. In addition, there is a mods directory in this location, which can be used to override system-wide mods.
