Thanks for your compliments.
Knowing that at least 2 people will buying a new different package feels good, but I will keep adding new content to the actual one. That is because I feel all the respective content should be in a single package or product. I'm not fond to the "DLC" approach xD
Also, after I finish the current updates I will add more environments, so don't worry about that. Of course, with the same style and keeping the quality as high as I can.
