Game Description & Manual: Collect the power-up orbs, it will add points to the ships' hull integrity. Try to do strafling runs at the enemy, that is, fly either to the left or to the right while firing. Lon bombs are only good when the enemy are close to you. If you find that can't fire your lasers, restart the game, even I got that problem myself. Finally even if your ship can withstand plenty of hits, try not to get hit too many times, the ships insurances' doesn't cover those.
