Line Rider does a figure 8 and a clover.
The sled comes really close to breaking a few times, but you can pull a lot of G's if your lines are smooth enough.
This game could really benefit from some better drawing tools.
I saw this awesome "pinch cannon" glitch at http://www.youtube.c om/watch?v=R887xDwIW 8A and had to try it myself!
Done on fsk's linerider beta (I really hope the next version comes out soon.)
Oh, I added music this time. Let me know if the music sucks :)
