Sorry about that, the route in that level is a little confusing. Basically you're supposed to trace a backwards m shape, starting at the lower right and ending at the lower left. Here is how the collision looks:
Gravity is supposed to pull you towards the lower left slope which leads to the next level. If gravity is pulling you right, it sounds like there might be a design flaw or a glitch. What browser are you using?
I'm trying to understand exactly is causing the issue, you should be able to walk left and get to the end of the level in the bottom left. If that's not working it might help if you post a screenshot.
