This is another Flash Sonic. You control Sonic the Hedgehog or other Sonic characters with the arrow keys. Press Z or X to jump. Remember that Sonic is vulnerable in his normal state, but causes damage when rolling. Sonic is rolling while jumping or running fast. To start a rolling run you need to me space to accelerate. You can play the built in levels or load a level from the network. Some network features are only available if you register.
