5 stars: Though a bit crudely made, I enjoy the gameplay of this game a lot than the more 'polished' forging/selling games. 4.99 seems a bit too high to remove ads. If it was 2.99, I would definitely purchase it. I see potential here, though. So if you keep making improvements, I may find 4.99 worth it. Either way, I intend to keep playing.
3 stars: I really like this game, I even paid the 5 dollars to get it ad free. I feel a little ripped off/annoyed though, about 30% of the time when I get a good mix, it glitches and I won't get it and am unable to add it to my shop. I just had a mix and was lucky enough to get 3 electrum in it, and it glitched and wouldn't let me add it. Entertaining but definitely NOT flawless at all.
3 stars: There is an immense amount of advertising. It lacks progression after the first 40 minutes of playing. It's fun, however it would be more interesting with some sort of storyline, other than very minor questing. Additionally, the ore excavation is a little random, it would be nice to make a little more custom. I would be very happy to play this game again if the amount of ads is reduced and there are some updates in the future.
4 stars: Credit where it's due, they respond to your feedback quite well but they ruin the game with the banner asking to collect your data. other improvements may be to make rare ores more available or make the quests more rewarding. Many people are asking for some of these things. This game has a lot of potentia...
