This is the sequel to the House (If you haven't played It do it now) It isn't as big, but I'm still proud of it. Also drag your Mouse over the arrows. On some you'll see a button that says, "Launch", "Go to Earth", or "Go to the Moon". That lets you travel back and forth from the Earth to the Moon. There is a Launch vehicle, a spaceship, a Life support base, a greenhouse, and a rover. Also let it refresh for a second.
For my next project like this, comment what I should do. Idea I like most is what I do.
