Mini-Ludum Dare #37 was about making a not-game.
At the time this contest started, I was thinking in learning the ropes with the physics in Construct 2, so I got the idea of creating a non-game, where you can learn about it.
Set the gravity, density, friction, torque and elasticity and see how this affects the ball.
I appreciate any feedback, from how did you find useful or if you find any bugs or problems.
I personally was amazed how small changes in Elasticity make a big difference to the ball behaviour, whereas Friction doesn't seems to affect it much.
