This is a simulation really similar to Moon Landing. Moon Landing -> https://scratch.mit.edu/projects/177342965/ (Extreme lag!) This is not laggy! You are flying a hovercraft over a hill (?). The physics are totally off. Here are the controls: ----- [Left Arrow Key] → Right engine on [Right Arrow Key] → Left engine on [Up Arrow Key] → Both engines on [Down Arrow Key] → Retro rockets (?) ----- Retro rockets produce SLIGHTLY more lift to overcome the gravity. Enjoy!
