||If you use this, please switch to using 'TD' for that game now.

This is the primary goal that people will have in a game when starting to play it.
||Being at the bottom of the screen all the time while playing, a tendency that newer players often have, due to being afraid of the bullets and
wanting to be as far away from them as possible. While sometimes useful, this is not always the best general strategy.
||Bullets being converted into items, effectively wiping them from the screen, which is often important for score.
This occurs when the player ends a boss pattern by shooting the boss, but can have several other causes too, such as enemies that cancel their bullets when killed, or bombing.
||Abbreviation of 'capture'; a Spell Card being dodged without dying or bombing, which awards a Spell Card Bonus.
||Dying because of wrongly estimating bullet hitbox size(s).

||Dodging waves of bullets by going around them rather than through them, which may or may not be to avoid having to micrododge.

||Personal Best; someone's highest score or best survival in a specific category.

Resources are often denoted with the 'x/y' notation, for example 0/0 for when the player has no extra lives and bombs left.
||Changing your streaming direction, usually by making a quick, unfocused movement to misdirect the bullets
and then streaming into the other direction. Also known as 'cutback'.

If a player comes close to either edge of the screen while doing this, they will want to restream the pattern.

||Tool-Assisted Speedrun; used to refer not to speedruns, but to runs that used cheats, such as slowing down the game, using savestates and pause buffering,
which is often done to see what is theoretically possible in a game.
||When a negative number is converted to a format that does not have negative numbers, causing a very high positive number. Notoriously occurs in DDC

a counterstop. Not to be confused with overflow.
||A cluster of bullets with no space that a hitbox can pass through in between them, although it can also refer to a cluster of bullets that looks like that.
