This is an extremely minimalist, retro arcade game in which you only have one goal - to stay alive.  You do this by avoiding the enemy critters and making them crash into each other as they try to home in on you.  

Features:

• 5 game speeds
• 2 game modes
• 20 levels
• Challenge mode (play through all levels)
• 8-bit SFX

If you need pretty graphics you'd best look away now... apart from the menu screen, all I've got for you is coloured rectangles...
