Linear Balls
About
This is as fat as I got for now. I build this engine myself, from scratch on C++. I calculate all pixels myself and only send them to OpenGL to display it on screen. You can spawn balls by pressing B. Pressing G adds gravity, F removes it. I think it's kind of impressive how convincing it looks. Balls are 1 kg, 1 m diameter, and are absolutely elastic in this game. Just don't spawn more than 100 balls!
You can even mod your own ball! If you change sball.tga image!
