Lit Up

It's a nice and simple puzzle game with a simple objective, just light up all squares in the room. The mechanics are simple, but sometimes it's not easy to combine them. The puzzles themselves are not too difficult, but don't underestimate them... all you need is to think a little bit, really. I do enjoy puzzle games, but I'm not the sharpest tool in shed so it took me a while. Go for it if all you want is to kill some time, it's a nice and simple game.
