I had a wonderful time with this game! It has everything I love: retro flair, tricky puzzles, and robots. I've gotten all 25 gems now!
I think the main reason people don't like this game is because they don't have the patience to sit still for a couple minutes and think. Maybe another mindless sniper game would be great for these people.
