So for a while now I've been playing a game called Close Your Eyes and it is such a great horror game about a murderer who escapes it's death sentence. The graphics are super simple, but also unique. The gameplay is awesome, with a mixture of easy parts, but also some hard ones. I suggest you play all of this developer's games. I'm promoting it, because I believe that for a free game, it is great and this game developer shows perfectly that you can make a great game with really simple graphics!
