The graphics are top notch. Kingdom hearts has a strong art direction that relies on exaggerated characters and cartoony effects rather than realism. Everything is colorful and the levels are fun to traverse. The character animations go a long way in giving each character you meet a distinct personality.
The combat is just as fun as it was in KH2. With special abilities to equip and D-Links which allow you to power up with the help of a comrade, the action never gets old. I'm playing on proud mode which requires that you actually utilize all the moves at your disposal.
There's something to be said for some of the quirky titles that feel at home on a handheld; Puzzle Quest, Patapon, Lumines... but I'm glad a console experience can be translated smoothly to the PSP.
