StackerBeam

The game takes place within two phases:

Phase 1:
Press [SPACE] during the stacking phase to drop boxes.
Stack boxes on the platform as high as you can. Once you miss, boxes stacked are used as ammunition for Phase 2. If you miss with no boxes stacked, the game ends.

Phase 2:

Press [SPACE] during the shooting phase to shoot laser blasts.
Shoot all the UFOs on screen! Running out of ammo or clearing them all returns you to Phase 1. Shooting UFOs will slow down the speed of the boxes in Phase 1, so shoot as many as you can!

As you play, boxes and UFOs get faster and faster. See how far you can go!

Green UFOs have a chance to give you powerups:

• Stack Aim
  • Stage 1: A laser sight on the platform to aid stacking.
  • Stage 2: Along with the laser sight, the platform is wider.
• Jumbo Blast
  • Stage 1: Laser blasts are larger, making UFOs easier to hit.
  • Stage 2: Laser blasts are even larger!
• Shatter Blast
• Stage 1: Laser blasts release shards upon impact.
• Stage 2: Laser blasts release even more shards on impact!
