I really enjoy such puzzles. I had a 2 off. Fortunately, the 2 cut was obvious. Really fun and since I got it on first try, could give it a 6th star... LOL It seemed so simple until the layers kept revealing. Incredible little level! 83 was not a problem, but 81 gave me a bit of a problem. :)) Very nice one! Reached the exit immediately but still can't optimized
