N-body simulation, using only spheres, and has a basic physics collision system and orbital physics Made some optimizations already, to allow it to run at 30 fps, but still working on possibly using the barnes-hut algorithm to make some really large-scale simulations while keeping it at a playable frame rate. I highly recommend turbowarp, but you can still play here Also working on adding interactive stuff, like dragging particles and spawning them at the mouse.
Click and drag to move the camera, and scroll up and down or use the 'zoom' slider to zoom in and out HIGHLY RECOMMEND TURBOWARP, AND TURBO MODE(see inside-->edit>turbo mode)
