Select and inspect
Choose an object to inspect it. Drag an object while paused, or press Run to begin the trial.
Control the Pusher
Press Run, then use ← → to move. Press ↑ to jump when gravity is on.
With friction, the Pusher walks. Without friction, the jetpack provides surface movement and left/right control in the air. With gravity off, use all four arrow keys to fly. Release the arrows to brake.
Camera follow starts on so the Pusher stays in view. Turn it off in Appearance & Display.
