Multigrain Madness

You are Dr. Fabian, an astrophysicist with a focus on dimension physics. You wake up after a failed experiment in the most classified secure part of the ship as the only sole survivor. You have no way to contact the captain and need to traverse your way out of the complicated security pathway to the bridge and hull. In order to traverse dimensions you will need the dimension traverser: a portable toaster-shaped device that uses different bread to cross dimensions
