Its basically like a cloud storage, and your local storage (your brain) gets wiped every loop. You can edit this file any time you want using your brain (you can be tied up and it still works). 1024 Bytes is all you get. Yes you read that right: BYTES, not KB, MB, or GB: 1024 BYTES
Lets just say, for this example: The loop is 7 days form a Monday 6 AM to the next Monday 5:59 AM.
How do you best use these 1024 Bytes to your advantage?
How would your strategy be different if every human on Earth also gets the same 1024 Bytes “memory buffer”?
You can fit quite a lot of plain text in 1kb; it’s really just a 1024 character message. What you’d want to store would really be dependent on how the day went, but starting with “You are in a time loop. It resets every week on Monday at 6AM” would probably be sufficient to get things rolling; that’s only 61B.
I’d just add information that helped me have the best 7 days possible - really just a schedule of things to do. Did I read a really good book? Note that down, read it every week, enjoy that time. Did I play a great game? Same thing. Once I found 7 days worth of activities that were maximally enjoyable, I’d be happy to just stay in that time loop forever; the memory reset is really a blessing, not a curse.
But you’d need to spend some of that memory convincing yourself you actually were in a time loop, or you’d spend the whole time thinking the memory is some weird dream.
