This is a Multiply or Release! The variables next to the cannons with numbers are the number of bullets that the cannons has. If it's x2, it multiplies the amount by 2. If it's bullet, it shoots bullets that has a 50% chance to disappear if it bounces. If its Missile, it shoots a missile that automatically hits the opponent's core. If a enemy projectile touches the other core, then it lowers its health by 1. Pick a color and if the opponent's core explodes, you win!
note: this is not a playable project, just something you can watch and bet on with your freinds.
