5 stars: There's no ads and I love it and it's so fun and I love it in the more times you upgrade the thing that needs oxygen to make a coin and everytime you upgraded and makes it even higher than it was before
3 stars: Could be fantastic but the interface/controls are too awkward with poor information relay, makes it feel messy to play.
4 stars: Awesome game but the upgrade tags disappeared and I don't know why but besides that great game.
3 stars: A good game but the problem with the star rating is that when i make the hammers to fast it bugs out the volcanos and it made it so that it dosent always make bubbles when a hammers hit it so i need you to fix that problem
5 stars: Needs to have special connectors to make the running of air tubes easier, a screen just for upgraing the different items. Other than that it is a great game.
5 stars: Great Game, and make more machine. Remember the possibilities is endless 👍
