Tips
Don't be tempted to rush for power-ups straight away - save them for when you really need them (and when there isn't a barrage of bullets around them).
Tailor your upgrade points according to your style of play - it helps to have extra health if you're risky, while more cautious players can benefit from extra shot spread.
Try to focus on enemy fire rather than your own projectiles - even when blitzing a wave of invaders with your laser, you can still get hit.
