I think the problem is your games being animal-related, since the new policy has taken hold.
Saw other developers doing the same thing and had no issue having their projects indexed; also there is no rule prohibiting promotion of other products. I spent a lot of time trying to figure out the problem myself and found that I broke none. The deindexing was probably triggered by frequent bug fixes I did on the latest project but I can not be sure of that. Thanks for trying to help tough.
