  • Try to set the high score by killing enemies
  • Health and ammo are shared. For example, blue health is used as ammo for the blue gun.
    • Enemies can be hurt only by bullets of the same color
    • Red enemies give green health when killed
    • Blue enemies give red health when killed
    • Green enemies give blue health when killed
  • If any health/ammo pools is depleted, the game is over
  • The only wait to get more ammo/health is by killing the enemies
  • Enemy bullet colors determine which health/ammo pool is drained when the player is hit
  • Jump in mid-air to drop a barrel bomb
    • Barrel bombs hurt all enemy types


The theme for this game jam was Downwell's Dual Purpose Design

RGB conforms to this theme in the following ways.

  • Health and ammo are shared.  Every time the player shoots in an attempt to kill an enemy, their own health is drained.   
    • The amount of health/ammo for a particular color affects the bullet size.
  • Jumping in mid-air does a double jump and drops a barrel bomb which hurts enemies. 
  • Killing enemies grants the player points and refills their health/ammo pool.
  • Jumping on enemies heads refills the players number of jumps they can do and springs the player into the air.
