Factorians

Factorians is a vertical-scrolling space shooter where you shoot down numbers by recognizing their prime factors!

Instructions:

• Fire at enemies by launching Factor Torpedoes
  • Click a button on the bottom or hit a number (2, 3, 5, 7) and your targeting system will fire off Factor Torpedos at any enemies onscreen for which that number is a factor.
  • Higher levels: Use the letter i for 11 and the letter o for 13.
• Arrows keys: fly. Only necessary to avoid enemies and pick up coolant. (WASD keys also work, as does clicking on a target position.)
• Higher levels: When your Prime Bomb is unlocked in the lower right, click that button or use the Space key to launch a bomb that will eliminate all prime enemies on the screen.
• Press [ for previous track on the jukebox, ] for next track, \ to restart track. Backspace key pauses / continues music.

You start with 3 shields--green boxes in the bar on the left.

Watch your heat (green-red gradient bar on the left). Every time you fire you build up heat which cools down slowly. Too much heat and you can't shoot--screen will flash red and a coolant flush will bring your heat back down soon. After the first level, a combo of 4 or more enemies will generate a coolant powerup.

This game is a prototype. This game isn't mobile-friendly yet; you will need to play on a computer.
