4 hours, not a terribly productive day. Head hurts, hard to focus.
Materials for bullet trails are correctly colored and assigned, for real this time. When a player is on multiple tiles at once so that a projectile would fire down a line that would convert two rows/columns of tiles in a single motion, the projectile's instantiation position is altered. The projectile now instantiates within the bounds of the tile that contains the majority of the player. Players are no longer eliminated by being struck directly by a projectile. Instead players are now eliminated when the tile that contains their majority is converted to the incorrect color. Well... at least it would if it wasn't broken. Currently even if a minority player holding tile is converted the player is eliminated. Maybe I'll fix it tonight / tomorrow.
