RUNNING THROUGH THIS WORLD AND NOT LOOKING BACK
The game is broken up into nine levels - each representing a major game from the series - and 2 acts; one for modern Sonic and the other for classic. The order in which you can play the acts is optional, but it is required that you play both to progress.
This may seem like a small amount of content, particularly because we were able to get through the entire game in about five hours, but there is a decent amount of Sonic for the budget $49.99 price-tag. There are tons of challenge missions to complete as each Sonic, some of which are entirely new levels within themselves. Completing at least one of these for each level is required in order to access the game’s bosses, and adding the rival matches against those “other” hedgehogs into the mix creates a nice concise game.
