This video shows an early build of the game. A lot of the sound effects are jittery, and some of the dialogue tends to lag. It also recycles a piece of music from Sonic Adventure 2.

Seaside Hill remains incomplete, lacking a platform required to continue through the stage. As does Sea Gate, which is missing large chunks of the map and appears to be unplayable.
