I love these Pixel arts-gives me a break from my other hobbies. My only complaint is the developer must not have much creativity. I am 66 years old and I don't want to do a cow, a bunch of rocks, a paint brush. For the money we are paying we should get quality pictures. I only end up doing half of them and that is stretching it. It is the same with the other Pixel Arts offered. You have to do the first page to look at the others so you buy a series without knowing what you are getting. My 5 year old grandkids could do most of them. If you don't mind getting mostly simple items to do then I recommend these games. I am still deciding if I want to get 13.
