Thoughts on the Heart Shop

When I first installed playio, I was curious about what I could exchange at the Heart Shop, so I worked hard on the main quests, but it turned out to be different from what I expected, which was a bit disappointing. ↓Here's a description of the Heart Shop lineup: ・Boost Items (5 Gems/30 min, 1 hour, 2 hours) ※Limited to 1 of each per month ・10,000 Experience Points ・Party Avatar (Icon) Was it too difficult to exchange for coins or gems? Devs? I would have wanted something like that, even if the point cost was really high. If that's the case, I thought it would be better to open treasure chests than to open the shop...
