Very funny, really quite effective Solid; has some decent ideas, and routing requires some thought The solution isn't bad, but the rest of the level isn't nearly tempting enough. Nice one with several clever optimizations Wow, great solution, very satisfying and gave me disbelief as I watched my path turn into a solution Simple puzzle, tight construction, neat cuts Silly little level, making me forget fundamentals It's quite easy to figure out, and I would like a level that uses more of the blocks better, but it could be a solid premise for a level. A lock with some nice internal action, nothing more
