What is Rock Blaster?
Rock Blaster is a space shooter drawn in glowing vector lines. You rotate and thrust a small triangular ship that keeps drifting, firing at large rocks that split into smaller pieces when hit, while enemy saucers hunt you. Each wave ends when everything is destroyed, and the goal is the highest score before you lose your last ship.

Rock Blaster drops you into a space-rock shooter in the style of the old vector arcade cabinets. Your ship is a thin triangle, the rocks are tumbling outlines, and the screen wraps at every edge. The catch is that shooting a big rock does not clear it. It cracks into two smaller, quicker ones, so the field gets more crowded before it gets empty. Add drifting momentum and saucers that shoot back, and every wave becomes a juggling act. Frank Force made it for his LittleJS Arcade, and it plays unblocked with keys, a pad or touch.
Waves, Rocks and Saucers
You start in the middle of the screen, flashing briefly to show you cannot be hurt yet. Large rocks float in from the edges. Shoot one and it becomes two medium rocks; shoot those and they become small rocks; shoot a small rock and it is gone.
Wave one holds four big rocks, and the count rises by one per wave. Nothing advances until the screen is free of rocks and saucers alike. Up to five bullets can be in flight together, and each disappears after about 1.5 seconds.
Two saucers show up from time to time. The big one sprays bullets in random directions. The small one leads its shots toward where you are heading and gets more accurate as your score rises. Saucer bullets can also break rocks, though you earn nothing for that.
Losing Ships
Colliding with a rock or saucer, or being hit by a saucer bullet, costs one ship. The LIVES counter begins at three, and losing a ship with nothing left in reserve finishes the game. Your record score waits for you on the title page.

How to Stay Alive Longer
Momentum is the enemy. The ship glides for a long time after a burst of thrust. Use short taps and turn to face the way you want to slow down.
Split one rock at a time. Every hit doubles the pieces. Mop up the small fragments from one rock before cracking the next big one, and the screen stays manageable.
Remember the wrap. Anything that slips off one edge reappears on the opposite edge, rocks and bullets included. A fragment sailing off the right can catch you from the left a second later.
Hunt the small saucer. It pays five times what the big one does, and the longer it lives the better it aims. Take it out quickly.
Hyperspace is a gamble. The jump puts you somewhere random, clear of the edges, with a brief blink of safety, but it can still land you close to a rock. Use it when a crash is already certain.
Classic Feel, Clean Presentation
The vector lines, optional glow and crisp generated sound effects make Rock Blaster look and sound like a lost arcade cabinet. The menu has a volume control and a switch for the glow. If you want more space shooting, Planet Protector adds rescues to the mix, and Andromeda Invaders brings a marching alien fleet.
Rock Blaster: questions players ask
Is Rock Blaster a copy of an old arcade game?
It is an original take on the classic rock-shooting style, written from scratch by Frank Force. You still turn, thrust and shoot rocks that break apart, with saucers and a hyperspace jump, but the code, look and sounds are all his own.
Which targets give the most points?
The small saucer is the big prize at 1,000 points. The large saucer pays 200. Rocks pay more as they get smaller, with 20 for a large one, 50 for a medium one and 100 for a small one.
When do I get another life?
Every 10,000 points adds one ship. You hear a chime and the LIVES number in the corner goes up.
Why is the glow effect off on my tablet?
On touch devices the glow starts disabled to keep the game running smoothly. You can switch it on in the OPTIONS menu. On touch screens you steer with a stick at left and use four buttons at right.
