I was really excited at first but if I understand it correctly, we just hand in one item each day or whatever and can't earn any more rewards by finding more items. It seems kinda lame to me? And there isn't any point in rushing to get to the next milestone neither as the staff will be putting the next one up, it isn't automatic.

The animation is really cute and I can't wait to see what rewards we get at the end but I'm kinda disappointed with how little there is to do. They could have added some small rewards for people who want to grind for more of the items.
