Totally agree. It is more difficult to compose good logical puzzles than to solve them. I contribute far less now because of the frustration of weak players awarding 1 star to knock challenging puzzles off the scoreboard which makes it not worth the effort.
I agree. If someone makes a great puzzle you should give it 5 stars. It is good to have a challenge every now and then. So what if it is hard? If it is logical than enjoy the puzzle. If it is too hard for you, you can always get back to it later.
Sometimes an image can take a long, long time to test. I'm okay with a few 1-star markers. To me the reward is hoping to see some nice comments - they're the ones that count and make me smile!
(Those that gave it 1/10 at the beginning are clearly incompetent.)
