Finished Lemmings Touch on Vita. About to go blind (my eyes are literally twitching). The difficulty gets crazy in its demand for accuracy... Like if there's one pixel between a bridge you're building and a platform, the Lemmings will fall through. But then if you give a command one micro-second too late, the Lemming will move on and not be where you need him to be... And the cannons/trampolines are super fidgety -- some of those levels need pure luck, on top of perfect execution!
But for the sake of nostalgia, I persevered. I'm now one of two people who has completed the game on PSNProfiles.
Edit: One of three now. Someone just synched their trophies and according to the dates, he/she earned them earlier than me.
