Rules on what "changing entity"

After a stressful day at work I just want a little nap but as I get home I get kidnapped and sent to an island with other pepole, the island has no rules whatsoever and our only task is to survive or die trying, would be easier or hard (depends) if I didn't get this stupid but sweet system that wants to torture and help me, Yes the system confuses me sometimes

Go on roast me for making this novel if you want, I only wrote this as reference for when I am writing the book
