I haven't had the opportunity to mess around with Chaos Stream just yet but I must say, it looks like it's going to be more fun than a barrel of monkeys. A delightfully old-school looking ascii shmup, Chaos Stream is also powered by the roguelike development library, libtcod. While not particularly ground-breaking, Chaos Stream is deliciously retro-looking. I'm also impressed with the fact that it appears as though the developer has restricted movement to character space as opposed to merely utilizing ASCII graphics.
