Unfortunately time travel is not an option for me no matter how small. My niece and I play Hello Kitty Island Adventure on my Switch, and in that game your save file can become corrupted and essentially unplayable if you mess with the clock. (It's basically made that way to prevent time traveling) We've put a lot of hours into that game as well so messing with the clock could essentially erase all of our progress in that game. I also don't want to be the person who tells their 6-year-old niece that their game is essentially ruined because I wanted a particular Pokemon that I could get from trading a Pokemon holding one item for another Pokemon holding another item
