This game is simple, easy and addictive. I really love "gathering" and stuff like opening chests or looting in games and gathering gems has a nice similar feeling. I think the gameplay is easy enough that it isn't frustrating and annoying to play. I think it's designed well enough too, the interface is easy to use. However i have a few issues too. I can't open my bag to see my inventory, when i tap it it glows the icon up but it never opens. I also can't adjust the volume anywhere. I like the digging sound but not the sound of tapping the shovel. It's really loud too. I also see gems coming out when i pick them open but the count of those gems doesn't go up for the "customers" on the screen who give you coins. So im at 12/16 morganite, i visually see 4 more morganite and they don't show up. The count doesn't go up. And i can't check my inventory. So that makes me feel like my progress is being thwarted. I also wish it was easier to tap the shovel, it's hard on my wrists to hold my hand so close to the bottom of my phone. Overall it's a fun game i enjoy opening up whenever i need something relaxing and easy to play to enjoy some free time. I hope they will fix some of these issues and also give the customers a little more detail, i think it would be fun! Like giving them names or something to color them out a bit more.
