What a great game! The digging was really fluid and felt great, yet each of the upgrades made it better. My only gripe is that I missed some treasure under some tiny rock somewhere and spent an inordinate amount of time searching for it. Some kind of radar, or not requiring 100% of the treasures to unblock the next area, or something would have made that much more pleasant. I managed to get them all in the end though, and the fun ramped back up after a couple upgrades. The art was great, so much variety and motion!
