Concept

Your ship can be one of two colors at any given time: black or white.  The color of the bullets it shoots will match the color of the ship's current color.  

The enemies encountered in the game can be one of two colors: black or white.  If they are black, they will die only to a white bullet and vise versa.  Certain (Dual-Coloured) enemies will be half black and half white at the same time; your ship must shoot this type of enemy with a bullet of each color to destroy it.

Enemies

Spinner - Shoots the player at random intervals.

Vista - Dual-Coloured.  No special behavior.

Sploder - Explodes after an elapsed period of time, sending bullets in all directions.

What's new in Version 0.3.5?

Added score text for destroyed enemies.

Gave the Sploder enemy its own sprite.

The Spinner enemy now shoots at the player.

What to expect in a future (possibly the next) update?

More enemy types (Maybe)?

A TRUE endless gamemode (one in which the sequential waves progressively increase in difficulty).

Note: This game is a WIP (Work In Progresss).  See news feed for more info.
