New Features

Added particle effects to enemies when they are destroyed.

Particle effects can be set on/off in options – saved to .cfg file

Added screenshot counter to .cfg and options so screenshots will no longer get overwritten.

Added 3 new bomb powerups using particle effects to Arcade mode.

Added L1 for Pause.

Added moving squares to splash/menu, options and credits screens for fun.

.cfg file format (so this is the last time you should delete your .cfg file!)

Features

Classic, Arcade and Survival Modes with unique high scores for each.

Option area to select analog desensitivity, turbo adjust and slow adjust.

5 powerup bombs (random bomb appears every 10 points).
