About this game
Shoot all enemies and move on to the next level. On every 10th level, you will have to defeat a more difficult "boss" enemy that shoots orbs and brings down a beam toward the center line. You lose a life if one of those orbs or beam hits you.
This game gives the player the option to play from 3 levels of difficulty:
- Easy mode:
- Player can shoot unlimited bullets.
- Normal mode:
- Player can shoot 2 bullets at a time. Bullets must hit enemies or disappear at top/bottom of the screen before player can shoot another 2 bullets.
- Hard mode:
- Player can only shoot 1 bullet at a time. Bullet must hit enemy or disappear at top/bottom of the screen before player can shoot another bullet.
You also have the option to toggle between windowed/fullscreen mode and toggle music and sound on/off.
High score feature automatically saves your high score at each level throughout the game and loads the saved high score next time you play.
