I have a "tradition" to 100% this game at an average of once per year. In some aspects is pretty superior to other platformers from it's era while it lacks in some aspects compared to others. I'm not sure if it has aged as well as I think but is very fun to play once you get used to the movements and the surprising speed in which you can finish a level.
This is a classic for sure and one of Rare's best games from that time, flaws and all; level designs is colorful and fun, music is sublime and characters are full of personality, the final boss fight is long and hard but a learning experience that becomes very rewarding when beaten.
I just love this game a lot and is such a breeze to play every time for me.
To close I'd like to recommend the XBox version a bit more for first time players, since it adds some quality of life improvements.
