Sonic Xtreme 2

This game allows you to play as Sonic, Tails or Knuckles. Once you complete the game, you can also unlock the ability to play as Amy or Shadow.

Choose your character and the action will begin. You'll be dropped into the first level with a large line of golden rings in front of you. You can move with the left and right arrows. If you choose Tails, you can launch into the air with the up arrow. The easiest way to collect this line of golden rings with Tails is to hold down the spacebar and use the right arrow to glide through them.

When you encounter enemies, you can also use the spacebar to take them out.
