I started playing this because I was getting frustrated at the PS1 Ape Escape controls. 6 years of hindsight somehow did not work the magic I thought it would've and the controls for this game are somehow WORSE. Couldn't get passed it and went back to PS1 Ape Escape with newfound respect. Though, for the niche of people who don't own a PS1 but own a PSP - it's Ape Escape. Also the voice of Billy from Billy & Mandy voices your character.
