I had just finished Blind Forest before Rise released. Needless to say, I haven't played Wisps as of yet. Blind Forest is perhaps one of the most beautiful and enjoyable games I've ever played. It was definitely tough to a point of aggravation in a couple of the "escape from" encounters, yet once I made it through, the sense of accomplishment was immense. If Wisps is as much of an improvement over the prior as you say, I might just have to put Rise down for a while.
