Not as bad as Sonic 1 in my opinion, but not even close to being as good as Sonic 2 or any version of 3.
Sonic CD has a cool intro, a few decent levels and some neat ideas, but it still suffers from some questionable level design that seems like is trying to make you waste your time rather than complement and reward your speed and skill.
The time travel gimmick is a cool idea on paper, but it isn't well implemented. Sometimes it is impossible to time travel because of the way these levels are designed, so you have to pray you find a random corner of the map with two springs you can constantly bounce off of back and forth, in order to time travel. A very superficial way to build speed and solve the issue of the game stopping you on your tracks constantly.
I did finish it but I never even bothered to get the "good" ending.
