Megapixel Multiply or Release 9

Four colours, controlled by marbles, battle for control of a 1000x1000 pixel grid.
Marbles start at number 1, and multiply in value when they enter the corresponding green triggers. If they enter the red triggers, their number will reset to 1, and the number that was reached will be launched as either a burst attack or a charged shot.
Burst attack will fire shots equal to the number reached, up to several hundred or thousand shots per second depending on the number of shots still be to launched. Any subsequent burst attacks will increase the number of shots remaining. Each shot will convert one territory pixel to the player's colour.
A charged shot will combine the full number into one large shot, which will convert territory pixels equal to its number.

The charge can also be used to replenish the player's shield. The shield blocks any incoming shots, and takes damage equal to the shot strength.
