This level is basically a tutorial, and a damn short one at that - the tunnel to the exit is right above where the Pulse Cannon part is, so it's just a matter of flying through that and it's a straight shot out of the stage from there.

After every level, we're greeted with this rather basic score screen where an octopus stares at us menacingly... why? I have no idea - it's probably not a normal octopus since Dr. Riptide's been doing weird experiments on everything... it's why there's so many critters trying to kill us down here.
