I made a pathfinding course to experiment with the new checkpoint feature. It's called Green Eye Grid

I don't want to strategy hoard, and I'm pretty sure this only comes into play in custom levels: The order the game checks you hit things is not based on distance along the step. Instead, it's checkpoints, then goals, then walls. So in a level like this (or ) you can, in your last step, slam into a wall as long as your step line also hits all remaining checkpoints and the goal.
Edit: Okay so thorn and cobra venom both have shortcuts with this strategy.
