John Evans creates games that are very ambitious but generally not thoroughly tested. This gane, though, I really enjoyed.
You are a spirit summoned to a floating magic castle island. You can create anything! Well, actually, you can create whatever the author implemented. You are presented with six challenges, and have to guess what to create. I beat about 3 and a half on my own. At least one depends on you seeing something not in the room descriotion, which I thought was unfair.
