Complaints:
The arrow needs to have sharp corners -- I was going along the diagonal in the math bit.
If you are going to use the medalion/colour/slot via the lights, then MAKE YOUR COLOURS MATCH!!!!!!!
Other than that, AWESOME puzzles.
Never mind! You have to click on the ship after each chapter to start a new one. Don't go running back into the maze after a rescue. You have to get the chapter select screen.
