Because this is the first game, the only controls are jump, spin and the directional pad. Fun Fact, The original PS1 version used both the circle and square button as spin attack buttons.
Another fun Fact, Crash Bandicoot One could've been re-released on Wiiware had there not been copyright issues with Sony at the time. The game could've used the D-pad, 1 and 2 buttons with the Wii Remote turned on it's side. Crash CTR would've also been a cool game to release for it.
