Scoring

The score is the sum of the folowing subscores: (enemies killed by a kamikaze action warrants no points)

Damage done to enemies:
- damage (counting overkill) * combo

Enemy kills:
- base enemy points * combo * rank ( * 2 if overloaded).
This score is added when the enemy explodes.

Powerups gathered:
- 10,000 points * combo * powerups gathered

Graze:
- 60 * combo * number of grazed bullets (max 5) per second

Combo is increased by:
- number of grazed bullets (max 5) * 1.875 per second


The rank ranges from 1 to 20 (unless you're on the second loop), and you cannot gain more than 0.5 rank at a time unless your weapons are overloaded.

Rank is increased by:
- 0.012% of the damage you deal to an enemy
- 1/10000 of the score you get from killing an enemy (overload multiplier excluded)
- 0.5 when you earn a capsule from grazing

Rank is decreased by:
- 4 when you lose a capsule when hit
- 1.5 when you're hit without losing a capsule
