5 stars: I think I just love this. It's fun, not clogged with ads like almost every other android game, this is really good to have such a little amount of ads! So many games only care about the money and don't necessarily make a very good game anyway but fill it with ads after every level, this is good for once with very few ads. Thanks.
3 stars: Simple and fun game. Only thing is that the only way to get gems seems to be buying them which is just bad. Every currency should be possible to get for free aswell. Right now the gems are just real money with a gem icon.
5 stars: I love it. The only thing I want to say, is it is too easy from lvl 100 and on. I can just tap in one spot and get down to the core in 10 -15 seconds. Devs, you should add hardness to different parts of the planet. Not in layers, but different spots. Other than that, I have no other problems.
4 stars: Good game but I've earned all the bombs and now there's not much to do i think I there was a way to earn gems for the shop the game wouldn't fall off as soon as all the bombs are unlocked.
5 stars: This isn't a review but a good thing to add in the game would be if you use the rocket it leveled up little by little except for the first one cuz it does it too fast and you could just sit there forever and keep on leveling it up
5 stars: So this game has tons of ads, But I have something to help you if you get annoyed by the ads, Just turn off you Wifi! that will block the ads so you can play ...
