The game has over 100 levels and your pet can level up through training. You can check out the system requirements here. The game is entirely FREE to play unless you want to purchase extras. The extras that you can get are for a cash purchase. You only need to have internet connection long enough to sign up and login. After that, you don't have to have internet connection to play the game.
The game starts off with just the octopus for the pet that you're required to train for battle. You will be asked to choose and design your avatar. When going through the vortex you will need to press the up button.
The game is a little difficult for first time players that have never played a game like this one. Especially on a smartphone.
