Right, short description from watching it being played.
The Life is Strange time power seemed to follow along roughly two different types of application.
The first, allowed for the user to rewind time for a limited* period, accruing strain as the rewind progresses. This strain resulted in headaches, nosebleeding, and eventually power failure.
*Actual limits nebulously defined, but likely more on the order of 'minutes' rather than 'days'.
The second, allowed for the user to, by focusing on a photograph, go back to the time at which the photo was taken. There was no demonstrated limitation for how far back this could go, but there did seem to be some manner of snap-back mechanic where after effecting the immediate situation you would flash forward to roughly the time period when you left, without your memory updating for the changes resulting from your alterations.
I will recommend against using Life is Strange for two reasons, however. The first, is that the main character does
not have a good time, and we will almost certainly be facing san damage if we go through that route. Probably one of the big causes for san damage will be getting drugged and trapped in the Dark Room... which actually seems kind of likely to set off our trigger as well.
The second reason is that, in story, time reacted extremely negatively to the alterations. A fair portion of the plot is from an impending tornado coming to wipe out the town as a part of an escalating series of consequences from saving a single person. Other effects included multiple moons showing up in the sky as timelines started to intersect, and the protagonist at one point falling unconscious and being trapped in a
Nightmare.
