So if you don’t know, there’s a pretty decent game on Kongregate called Defender’s Quest: Valley of the Forgotten.
In terms of demos it has a huge amount of content, and even that only scratches the surface of the game. You could probably get 30-40 hours out of it, going through the normal game and New Game+ content. I think it costs 100 or 150 kreds to purchase the full version on Kongregate, well worth it either way.
If you’re already a fan though, they just put up the site announcing the sequel, and already it has a bunch of interesting stuff on it. :D Well worth the read through, I think. They have the guy behind Dust: An Elysian Tail on the art team, so my expectations are through the roof.
