MasonicGamer.com: Episode 2 is a bit of a blast from the past. Nostalgic sounds, level design, and boss fights give the game a strong feeling of familiarity. Clocking in at a short 4.5 hours of single-player campaign, Episode 2 is short and sweet; only 4 full levels long. Each level consists of three acts and a final boss giving the game 16 total stages. Once you complete all 4 of those levels 5th final level appears with the 2 final boss fights.
The coolest thing about Episode 2 is the presence of Mile “Tails” Prower throughout the game. Together Sonic and Tails can team up to perform combination moves, the first of which is a tandem flying ability that doubles as a submarine when under water. These abilities make hard to reach places far more accessible and also gives the player a few new ways to take on bosses. The duo combines to make a fast and deadly spin attack for the third ability.
