Spectacular level! I had a lot of 4-offs and a 2-off, and it turns out I was missing an imo really subtle way to save 2 more. Indeed this is better than the other version (which wasn't bad, but this was extremely hard to spot).
Astounding level! Even when you find the sneaky path, it still takes a while to optomize. I don't normally say "this level should go in the game", but this level should go in the game.
13 years later, my opinion is the same. Solving this was just a-ha moment after a-ha moment, with plenty of being stumped sprinkled in.
