Essence of theTool-Assisted Speedrunner

You can speed up or slow down your own perception of time at will. You may choose to freeze time entirely and advance the world one Planck time at a time if you wish.

You can move backward on your personal timeline at will. In other words, if it is currently Tuesday, you may return the world to the way it was on Monday, with the only remnant of Tuesday's events being your own memories. You will be returned to the exact state you were in on Monday. There is no limit on the frequency or length of your movements.

You can create "save-states," freezing the exact state of the universe into a mental object which you can freely load, restoring reality to that state, even if you have previously gone back in time to change the timeline so that that state would never occur. You may have any number of save-states.

You can save a series of actions that you have taken as a "macro" and automatically execute that series of actions again. If you execute the same macro from the same save-state multiple times, you are guaranteed to produce the exact same result. You can speed up your perception of time to instantly skip through your execution of a macro, if you wish.

These powers can never be taken from you and will always persist, even if you die.
