Concept is good, way to buggy. Definitely needs a ton of work. Upgrades that complete remain stuck. Can't tell you how many times I've have to close the app reopen just to continue research and upgrades if they fix the bugs games a 4 star it would remain 1 start out 0 if crypto wasn't involved this game is a copy of hundreds of others exactly like this one but the difference is the others work they just don't offer crypto. It's a copy and paste with crypto added no story just farm upgrade
