I get the idea. At least I think I get the idea. A game engine that’s easy to use, easy to modify, and keep track of checked out changes. More or less a retred of Wonderfl. Only this one is considerably more OO. And OOs good, right?
The problem is so few of the games have any sort of scoring. You can’t win, you can’t lose. The one that I’ve found so far has managed to get some sort of scoring mechanism in by working it into the world physics, and that’s brilliant, but this sort of cludge programming should be the exception, not the norm. Plus the controls are so… weird. Most of the games just avoid controls all together. You end up with little tech demos that play themselves. I think the idea has a lot of potential, but the execution makes me sad. But maybe I’m wrong. Go try craftyy out and see if you like it better than I did.
