Maybe add "Die" to the continue/reset cart menu.
Fun but the game can become unplayable:In level 03, start a flyby. The camera does not fully return to match the start/test zone. Click TEST with a rocketless robot and the core drops to the ground, and the "END TEST" button goes off screen.
Just a heads up, I'm seeing a small formatting problem.
That's how you flip a house. Why not a whole planet?
