Your health is not written when it changes, so it stays where it is. The table calls it Inf HP.

Keeps your character's invulnerability timer running, so hits do not land. Hold F to let hits land again for a moment (for spots that need you to be hit).

Hold Space to jump again in mid-air, as high as you like.

Enemies' health reads as 0 the next time the game checks it, so one hit kills them.

Weapon points are refilled to their maximum whenever the game changes them, so secondary weapons cost nothing.

Your score. Edit to set it. It reads once the game has drawn the score at least once after the trainer attached.

The id of the current character's secondary weapon. Edit to set it. The table does not list the ids, so try small numbers. It reads once the game has looked the weapon up after the trainer attached.
