Infinite rings:
You can stockpile rings by saving up 3000 rings, and then finding Wentos, the traveling merchant. If he
is selling Hero Sandwiches for the discounted price of 30 rings,
purchase 99 of them. You can sell them back for 50 rings each. Repeat
as desired.
How to defeat Dark Gaia:
After the cinematics, you will play as the Gaia Colossus dashing through Dark Gaia with the correct button. Dodge or smash the rocks to reach Dark Gaia and get closer. He will shoot a laser after awhile. When he is about to shoot, guard and move to a side to dodge it. You will get hit at least two times. You will then go into a “quick thinking” phase were you have to press the correct buttons. Dark Gaia will get a hold of you and you will play as Sonic. As you go through the Colossus, you will have to press the correct buttons to hit Dark Gaia’s big eyes. You will repeat the process two more times, and then stage gets more difficult. After you are done, you will enter the Super Sonic stage, where you will start to fly towards Perfect Dark Gaia. When you get near the Force Shield, Chip will enter the shield in the Colossus. You will then have to hit the snakes outside of the shield as their heads leave it. As you hit the snakes, Dark Gaia will attack. Avoid the rocks and lasers he shoots. After you knock out all the snakes, the shield will drop. Then Dark Gaia will grab the Gaia Colossus. You will now have to press the correct buttons to save him using Super Sonic. After you free the Gaia Colossus, Dark Gaia will shoot a laser at it. You will have to press a particular button a certain number of times to block it. If done correctly, Super Sonic will fly towards Dark Gaia’s middle eye. You can use [Boost] while flying there if desired. When it is over, your grade will be based on how fast you did it.
