Otherworld Travels

I've started buying keys to other worlds little by little. I sent my character to another world for the 3rd time today, and all 3 times it was the Ice Castle... (´･ω･`) By the way, for food, I gave them onigiri the first time, crunchy treats the second, and fish the third. I wonder if a difference of 1-2 hours doesn't make a difference in the destination? Maybe I need to send them on longer journeys~ 😅
