Sonic advance 3 is a game with a cool gimmick of tag teaming giving each character set unique abilities , great level theming, great music and bosses but the level design massively lets the game down for me as the problems with the level design in the first 2 games of having lots of cheap deaths is greatly magnified in this game and I didn't enjoy a lot of the game because of it. The tag mechanic is amazing however and some of the combinations are great and really make the gameplay feel unique compared to previous games. My favorite cominations where knuckles and tails and cream and knuckles but many other combos were fun as well such as tails gliding instead of flying when partnered with knuckles. The game also has hubworlds for each zone where you have to find the levels to access them. I love hubs in 3d games but I find these hubs pointless as they don't add character to the game and are tedius to explore. The chaos emerald system is better than 2 but still not great in my opinion. having to collect 10 chao in a zone is quite a lot but the fact that they save make them automatically better than the advance 2 system. Advance 3 adds to the dimps cheapness of pits and enemies with an abundance of crushing blocks that come back from off screen to kill you and I feel they have a wider killbox than they appear they should making this a game that often punishes you for trying to go fast and makes it frustrating to play for me. In conclusion the tag team mechanic is a perfect for creating great replayability but it's unfortunate that the level design actively makes me not to replay this particular entry, would love to see this mechanic to return in a game with better levels.
