the items collected in this way will always count as collected at the top,
so it is beneficial for your score.
The point items themselves also get more valuable as you cancel or graze
bullets at full power among other things.
The base (full) value of a point item is referred to as Point Item Value, or PIV.
It's displayed on the HUD next to the blue point icon. It can be increased by
collecting small Value items that usually spawn when bullets are canceled, but the
best way to increase it is through the Voltage system. PIV also affects some other
values, such as spell card bonuses.

The most visible part of the scoring system is the Power Surge mechanic.
While Power 4.00 is the maximum your shots will put out, you can overcharge
your Power meter up to 6.00. The surplus Power (and also the rest, if
you are in a bind) can be used to start a Power Surge (see `Controls`_).
you are in a bind) can be used to start a Power Surge (see `Controls`_). By default
a Power Surge is also activated automatically once your Power meter reaches 6.00;
this can be disabled in the settings.
The Power Surge will charge up the air around you with Danmaku electricity.
This boosts your damage by 20%, but you have to maintain the two kinds of charges
in the charge meter around your character. When the positive (yellow) charge
goes down and hits the negative, the surge ends. The special lightning items
that appear during the surge replenish both kinds of charges. By timing these
items you can control the relative amounts of charge and the higher your
negative charge, the more difficult the surge becomes to keep up.
While a Surge is active, all point items are collected at their full value regardless
of where they are on the screen, your damage is boosted by 20%, and your effective
Power level is locked to the value it was before activating the Power Surge.
The longer you continue this game and the more damage and negative charge you
stack up, the more powerful your surge will become. This will visibly increase
the radius of your sparkly aura.
Once the surge ends, all of it is released in a blast that damages enemies and
bullets. Be in the right spot when that happens, because all that havoc will be
transformed into collectible Voltage items.
To keep the Surge going, you have to maintain two charge meters, represented by a
ring around your character: the Positive (orange) charge and the Negative (blue)
charge. The positive charge starts at 100%, and the negative at 0%. Both gradually
deplete at different rates. The Surge will abruptly end when both charges are at
equal level. Both charges can be replenished by collecting lightning items, which
appear instead of mini-power items when you graze bullets; regular power items also
replenish charge levels.
These will increase your Point Item Value, give you 1 Bomb Fragment and also add
to your Volts meter.
Your Surge becomes more powerful the longer it's maintained, represented by a growing
sparkling aura around your character. The more negative charge you currently have, the
faster your Surge grows.
If your Voltage reaches the Breakdown level shown in the HUD, you unlock a
special spell at the end of the stage.
Once the Surge ends, all of it is released in a blast that damages enemies and
clears bullets. The damage and area of effect of the blast depends on how much power
your Surge has accumulated. You can manually cancel the Surge to trigger the blast at
the right time.
All enemies and bullets hit by the blast will spawn special Voltage items, which
greatly increase your Point Item Value, give you 1 Bomb Fragment each, and add to your
Volts meter. If your Volts meter reaches the Breakdown level shown in the HUD, you
unlock a special Voltage Overdrive spellcard at the end of the stage.
