5 stars: This is a relaxing game I use alot. But there are some issues. I only have had two so far. The Coelophysis having a broken left leg. And The Tyrannosaurus Rex's feet clipping through the base. Other then that it's been a enjoyable experience.
4 stars: This game is really fun and simple but I have just one gripe with it. The angle the camera is facing relative to the dig site makes it really difficult to see which blocks are covering which parts of the fossils I'm trying to uncover. If it was a more traditional top down view, or if I could freely move the camera around to see different angles, I would have no complaints. Otherwise it's just a solid time sink.
3 stars: The game itself is good. However as I have progressed I am noticing a glitch when attempting to get 50 more energy to complete a dig. I will watch an ad and get nothing. Most times it wants me to watch multiple ads and will not give me the 50 extra digs. If it continues I will be deleting the game as it is difficult to progress and I won't pay for things from a free game.
2 stars: I saw a similar comment to the issue I have with a reply that it's fixed but not for me. I'm stuck at lvl 1 with '10 more' displayed next to it but no matter how much I play nothing changes. I think there was a part of the tutorial saying I can spend the coins on something but there's nothing. No way to upgrade the museum or expand it. The game is fun but there's only so much time I can spend on digging up one skele...
