I just beat Sonic 2. I was sure I wasnt gonna be able to beat Robotnik but I got him on my second to last life, after burning through 8 lives and then 6 or 7 continues. whole game is easy as hell til the final boss. I still prefer the first game. it seems like the emphasis was more on speed in the second game and its a little harder to appreciate the graphics. still, Casino Night is one of my favorite levels in any video game. there was a ton of excellent parallax scrolling throughout Sonic 2 and generally one of the best looking games of its generation
