3 stars: Fun little game, but there seems to be a bug with offline mining earnings. Even though my stats show a net positive after smelting use, and my ore goes up while offline, it tends to drop very quickly even when offline for only 10 minutes. The game says you should get offline earnings for 2 hours. If this is working as intended, it needs to be explained better in game. Otherwise, fix it please, and you'll get a better rating from me.
4 stars: Great time waster! I wish there were more instructions or tips on how to be successful but I'm slowly figuring it out. It's all tap control and point and click. Very easy game to play. Just not an easy game to be good at. I suppose the same could be, and is, said about blackjack. I would enjoy a far better tutorial explaining what to do. Tip, don't be afraid to sell your galaxy.
3 stars: I don't mind the gameplay being slow, but it is very inconvenient that a supposedly idle game only gives you 2 idle hours. This game requires too much attention for an idle game, and, unless you have insomnia, you won't be collecting any resources over night. I like this game, but I don't think I like it enough to give it this amount of attention.
5 stars: Awesome game, have been enjoying for a few months now. Everytime they update or change something it has been intuitive and the few flaws have been fixed quickly. I really hope they can expand further in the upgrades tab, l can tell it's still a few months or more before I can tackle...
