  * Joystick input.

o Main:
  * Configurable controls
  * Loading and saving settings
  * Loading and saving data

o Tile map:
  * Background images.
  * Parallax.
  * Object layers and scriptability.
  * Transition from one map to another.
  * Scripting.
  * Background loading?

o Sprites:
  * Speed up loading a bit / background loading?

o AI:
  * Implement D* lite.
  * Player char pathfinding.


o Particle Engine Alps (Allegro Particle System)
  * Damage display.
  * Group for flexibility.
  * Allow bitmaps as well as colors/shapes.
  * Explosions.
  * Spell effects.

o Scripting:
  * Wire it all up so game content becomes accessible in mruby.

| DONE |

o GUI:
  * A 2D UI elements / drawing scene graph was implemented so the GUI can be
    partially implemented in mruby.
  * Some not too beautiful widgets for menu and dialogs were implemented.

o Tile map:
  * Static tilesets.
  * Load tilemapeditor.org TMX maps.
  * Tile map tile animations, also in TMX 0.10 style.
  * Tile properties.
  * Tile map layers.
  * Tile flipping.
  
o Sprites:
  * Loading.
  * Coloring.
  * Positioning.
  * Shadows under the sprites.
  * Attack animations and other one-shots now work.

o Physics:
  * Implemented stairs. Need to use stair and invisible support tiles in tile map.
  * Bump based physics.
  * Physical layers.

o Asset loading:
  * resor and store subsystems, both already scripted.

o Engine: 
  * Built-in own XML parser so no libxml2 dependency is needed anymore.
