I bought it at the original price and quickly played through the game that weekend. I enjoyed the game (otherwise I wouldn't have played through it as soon as I did), but this is probably the price it should have originally debuted at. I think it would have gotten more attention to begin with at this price.
I hate to sound like a cheap skate but what is holding me off from purchasing is more of the fact that it is a short game. From the videos and user reviews I would gladly pay 9.99 for the game if it had more content. The consensus so far has been that the game could easily be finished in a day or two.
