This engine is awesome! So simple to use.
The mechanics for my test pong game are all there for 2-player mode. It was easy even to make the ball rebound off the bats at an angle relative to the location on the bat that it hits (the bat is convex)
I just need to figure out how menus work (from tutorial6), then make extras, like an AI player, an endurance mode (quickly accelerating ball, one player vs. wall. how long can you keep it in play?), an accuracy mode (moving target around the playfield, first player to hit it with the ball 5 times wins) and stuff like that.
Have a look:
