The best of the classic sprites for Sonic and it's not even close.

Super ambitious with the technology of the time, merging two games into one will always be cool and I like how even though it's still basic, they throw a bit more story between levels with the transitions.

I think it is the weakest of the trilogy though, with more zones than before being misses for me. Still some all time greats though; Angel Island, Snow Cap, Hydrocity, and Mushroom Hill are all super fun. (i guess it's alot of the S&K zones I find meh)
