Features sonic fast speed thrilling moments and new additions for Sonic in 2-D
However, Advance 2 also delivers some new issues in the gameplay. Of Course you love going in high speed with Sonic but later and harder levels will leave you with unexpected traps like no floor to keep running and die. And it gets annoying because while you enjoy Sonic in high speed, suddenly he can easily fall for enjoying too much of it. Another issue is that boss fights are more of a chase that make harder to reach dr.eggman's different machines and require a more precise timing in doing jumps. Also, if you get beaten by the boss you will have to restart act 1 and 2 for that world all over again.
Despite a few issues here and there, Sonic Advance 2 is still better than the original. However, Sonic Advance 3 is even better because it removes the issues from both 1 and 2 and that is why Sonic Advance 3 is the best of the series. Still, Sonic fans should definetely give a try to Sonic Advance 2 if you simply love 2-D Sonic gameplay.
