Easily my favorite of the classic Genesis games. Same great qualities as usual such as the amazing visuals and music. The main thing that stands out the most to me are the practically seamless transitions from zone-to-zone and act-to-act that does a great job at making the world feel connected than feeling like just a bunch of levels. There are also a lot of moments that really caught me off-guard, such as Angel Island on fire or the different seasons of Mushroom Island. In return the levels are a blast to play through minus a few stinkers like Marble Garden, beginning, and Launch Base to an extent. I really like how the special stages are implemented, where you have to seek out the special ring in the level, and Blue Spheres is just really fun with how it gets faster the more spheres you collect as a fun challenge. Overall like I said in the beginning, this is my favorite of the classic Genesis trilogy, and this is absolutely worth playing.
