It is difficult to describe this mysterious, whimsical game, so I will quote the iTunes summary, “Explore a dream-like world of eleven beautifully-constructed environments in this iPad adaptation of the classic desktop adventure. Equal parts puzzle game, playful toy, and living picture-book, Windosill rewards playful investigation with mysterious and beautiful surprises.”
My nine year old daughter saw me trying to solve a level, and soon we were both deeply engrossed in finding the solution. We completed the game together, and then she wanted to start it over again from the beginning. Her perseverance in trying to puzzle out each level was admirable.
Vectorpark, the company responsible for this game, also has other iOS apps, which you can view here.
