Genuinely have no idea why that’s faster. After a bit of playing around it seemed like one of the only reasonable things to try. It’s not as though it feels like it should be slower, but rather I just can’t pinpoint a reason why it would be faster. Trial and error was the only way here. :) Pretty neat level though.
Edit: I looked at it a bit again, and I get it now! Actually a very cool optimization. Neat!
