Putting it simply, this is a bullet hell shooter.

Features:

Procedurally generated enemies:
All the enemy sprites are generated in code, meaning millions of possible baddie images, every game looks different.

Random soundtrack:
By combining 11 drum and bass tracks the in-game soundtrack varies every level.

Evolution path:
The core of the game. Each path provides a unique power-up, giving the player multiple options and ways to play through the game.

Go complete those challenges and earn those medals. Enjoy the destruction.

<Edit - Thanks to everyone whose taken the time to play, vote and review the game. You've all made me warm and fuzzy you know, "downstairs" >

V1.1:
This update may take a little while to filter through the system, it's only minor amends, so if you're stuck playing plain old v1.0 you're not really missing much.
- Hi-Score text made smaller, as ZeoTerraBladeOmega broke it with his early epic score.
- Bug with certain challenges going over their max value should be fixed, thanks to Yatsufusa.
- On game complete your score is submitted automatically, thanks FoldingDuckling for pointing that out.
