Not worth playing, if playing idle games can actually be described as playing. Just wait enough time and you'll finish, no skill or thought involved. Of course if you don't want to wait theres always the paid option! The devs have done well in making "progression" goals force the player to spend premium currency and so you can often be trapped behind 2 uncompletable goals with the only way to finish them being to spend actual money. the game is just a cash grab and not worth downloading at all
