project
i re-started my old physics 'engine' a while ago
and now i think i should carry on working on it.
what i want to do at the moment is interpret joy pad commands to control my little ship

to do:
Projectile firing
- physics on the projectile
- control element to how many a user can fire
enemy creation
- based off current 'good guy'
- need anti-gravity system
- - maybe booster shots to slow descent
collision detection
- physics for rebound etc.
- side protection (prevent ship from flying off the sides)
