Joker: When you finally get past the first part of the game, and you get past a chunk of the story involving your new boss Lisa, her daughter, and moving on to minining, you're giving the chance to show people what you've got by heading into mining escapades with your gravity powers.
Morgana: This is another glorified tutorial zone. At first they let you float around and experiment with your powers, flying into orbs, drop kicking, and the like, for about a good 10 minutes, until a seemingly pointless tutorial drops on you, and then proceeds to tell you how to use the attacks that you've already figured out
Yusuke: The placement of the green mining orbs is rather quite drab. It gives you less of a sense that you're mining a peice of history, but more like you're cleaning up a gross infestation that has spread across the world. It really gives a visual feel of how the life of everyone has degrated over time!
Futaba: The gameplay at this point is kinda hit or miss based on your tasts. The way it works is you have to float in the air, aim your cursor, then hit the attack button. From here, you will divebomb the enemy or ore, and drop kick them using the "Gravity Kick".
For the most part this is okay, and gets the job done, but the game seems to over adjust and you tend to go flying past everyone and off into the ether half the time.
The kick tends to insta KO monsters, sometimes taking 2 or 3 hits for the harder ones, but some times it's better to land and go kung-fu happy on them with basic ground attacks just because it's faster to not miss multiple times, make yourself re-adjust, and orient yourself so you know where you are vs the placement of enemies. Due to the camera constantly floating and moving, it's easy to end up upside down, and get confused as the players as to where you are positionally.
