No actual goal, just walk around, try to achieve orbit. Arrow Keys or WASD to move and jump. If you get stuck, press space to reset. If you can't move, try jumping before you press space. The center of gravity is the black circle. This is a scrolling galaxy-style gravity engine. It's easy to use, if you want to make a game out of it. Orbit isn't perfect because the screen is rectangular... good enough, though. This was my remix shared project...
i made blob move across the screen
