But I just don't understand how you can love playing through it, if you play Jazz Advance after Jazz 2. I mean, Jazz 2 has 5 full episodes with more then 5 levels per episode, and those levels are extremely long, and you can take multiple passages to boot.

After such awesomeness, playing Jazz Advance is an eyesore. The levels are unimaginative and straightforward. For the last mission, they even took part of the Carrotus castle tileset and copied it straight over.

It's just terrible level design, the enemies as well. Floods and floods of enemies in places where they shouldn't be. And only one kind of enemy with different colors, whereas Jazz 2 had plenty of entire different enemies.
