Pixel Flow

Conveyor’s ready, Tanks are on standby. Tap to send a tank onto the conveyor so it rains balls onto pixel cubes of its own color. The number above its head is its ammo: that’s how many hits it makes. Run out and it leaves the stage; if not, it slips into one of the 5 waiting slots and, when you tap again, it jumps back on the conveyor to fire another round.
The conveyor has a capacity—push past the limit and you’ll need to wait. Send them in the right order, manage the flow, and hit the cubes to clear the board piece by piece. Simple mechanic, sticky loop: tap → flow → repeat.
