8.6/10
Pretty good game, the level design is good, I like how they're original instead of the rehashed levels of episode 1, the physics are a huge improvement from episode 1 as well.
But the bosses aren't good, you wait then get the chance to attack them only once, then rinse repeat. I guess superstars took some notes off from this game.
The OST is fine, the metal sonic theme is my favorite part from the soundtrack, but the others are good but I'm not going to listen to them all the time but they're good for what they do.
Episode metal exists, they're remade levels of episode 1 levels but you play as metal sonic. They do explain the new power that metal gets which is cool but they don't do anything with it, you can't use it in the game and probably due to metal sonic being a sonic skin with new sfx for when he runs and that''s it.
I did enjoy my time with this game but if they made the game longer and the bosses were like the classic sonic games, I would've loved this game.
