Patrick Klepek played Kingdom Hearts: Birth by Sleep at E3 2010, and he brought back this previe detailing his complicated relationship with the game series. Klep visited Cinderella, and says:
"Within moments, I'd run into Cinderella and her posse, providing me a moment of pause while staring at the PSP screen. Even though Kingdom Hearts: Birth by Sleep is running on a PSP, you could easily confuse it for Kingdom Hearts 2. The art style established in the Kingdom Hearts games continues to impress and works incredibly well on the PSP. Hey, I might not know what's happening during Kingdom Heart's cut-scenes, but that doesn't make them any less aesthetically pleasing to watch."
