When fighting boss' losing rings is always a worry.
A good way to go about this is to have one ring at a time.
This way if you lose it and cant find it your still able to pick up one of the other rings of the level.
This way you are less likely to run outve rings during a boss fight.
When playing multiplayer, use shadow the hedgehog. Then when you get to one of those bubble things at a gate that you need 2 people to pass, just use chaos spear on one of the bubbles and stand on the other and the gate will open.
Once you are able to buy the purple gem you will be able to activate this.
Hold R1 with the purple gem equiped.
Run forward and then jump.
Now continuosly press X sonic should jump in mid air.
Keep pressing X to stay in the air.
With each jump sonic will get higher and higher.
