 * Spring 2016 Lisp Game Jam
 
-** Game
+** Gameplay
 
-   Minimalistic Ikaruga clone with pixel art visuals.
+   Minimalistic Ikaruga clone.  The player can switch between a light
+   ship and a dark ship with the push of a button.  Bullets are either
+   light or dark.  When the player is light, dark bullets kill and
+   light bullets are absorbed.  Vice versa when the player is dark.
+   Dark bullets deal 2x damage to light enemies and vice versa.
+
+   For simplicity, the player will fight waves of enemies with a boss
+   fight at the end.  The next wave enters when the current wave has
+   been defeated.
+
+** Graphics
+
+   All graphics use the Dawnbringer 16 color palette.
+
+*** Player sprite
+
+    The player sprite is 16x16 and has 3 frames: moving forward,
+    moving left, moving right.
+
+*** Enemy sprites
+
+    Each enemy sprite has only 3 frames.  The first two are the normal
+    sprite frames.  Two frames are used so that the enemy can
+    "breathe" and appear as if it's moving and isn't just static.  The
+    third frame is flashed when the enemy has been hit by a bullet.
+
+*** Explosion sprites
+
+    Need both small and large explosion animations.  Perhaps some
+    explosion animation on OpenGameArt can be recolored.
+
+** Design resources
