The opening cutscene and transition into the gameplay was cool! However whenever I switch to the chef he immediately falls through the ground and I'm unable to progress. 

Very cool idea! As the game progresses, switching between the characters gets intense. The first time I played, I had no clue really what I was doing. Then the second time, no enemies showed up! I sat for a while, but is there no win condition? Part of the screen was cut off at the top, so if there's a timer, I couldn't see it. A win condition of some sort would make this all that much more fun to play.
