Play Sonic Epoch The Game
You begin on a ledge over several spikes. Clear the spikes and grab the floating golden rings by using the right arrow key to move forward and the up arrow key to jump. Make sure you grab the rifle in the air on the next ledge.
You can eliminate the first two bad guys you see by pressing the spacebar to shoot them with your rifle. Be sure you avoid the small spikes between the two shorter pillars.
Time your next jump so you can land and then shoot the bad guy. Hop up to the higher level to collect the four golden rings. Head up to the highest level so you can bypass the oversized bad guy.
Collect the big golden ring and continue to the next zone.
