I like this game, I like it a lot, I think the level design is much better than advance 1, but it does have issues. For some reason any time a different company works on a sonic game they think the biggest issue with sonic is its boss fights, and they need to change them.

That's not a thing though, sure bosses in sonic games are easy as hell and you can just juggle yourself on them until they die in 5 seconds. That's fun though being able to cheese boss fights is fun. This game tries to make them last longer and harder by putting you in auto run sections where you catch up and hit the boss. This doesn't always work a lot of them can be beaten immediately still and I actually like almost all of them except that stupid one in the sky level with the insta kill hand. It's harder than the final boss of the game. In fact the only reason XX is the hardest level in the game is because it makes you fight that one again.

Anyways outside of that I actually liked this game, though I would have put it down after 2 playthroughs if the game didn't give me the funniest completion reward in any game ever.

I never wanted to 100% any of the advance games because the special stage requirements and the stages themselves are the worst in the series, but I did so for this one because I wanted to play as Amy Rose, literally the only reason. Sadly she isn't as different as advance 1 but she is still fun mostly because this game overall is better than 1.

Honestly I think I like this game more than I should, but I also hate it more than I should at the same time because of the bosses.
Overall a great sonic game though.
