This rating is based on playing through the game on a Dreamcast.

The parts that are actually good are really good (some of the Sonic levels, the overall reasonably fun story) and the game is incredibly charming. What keeps me from being able to endorse this game in any way is what the actual experience of playing it is like... it's a real slog to sit through for a lot of reasons, such as cutscenes that are PAINFULLY slow and a lot of repetition amidst its multiple character playthroughs constructed mostly of reused content. Honestly, this could have been a really incredible game if they infinite development time and resources because the ideas are all there- for example, playing as Amy pretty much sucks EXCEPT for when there are level segments designed specifically for Amy, all of which are pretty cool but which make up like 10% of her campaign. The robot whose name I forget has cool gameplay ideas but a real lack of levels to make use of them and most of his bosses can be beaten by standing still and repeatedly pressing the attack button. You get the idea.
