It's a card game collection made with Unity 3D. It's my first game project. They are almost popular games in North America. It takes me about 6 months and the more complex game is the ass-hole. The more voluminous game is the Bull game with 85 000 code lines (including blank lines). I'm leaving as poor as hell so it's hard for me to get user but on Google Play i got rentention of 51% after 31 days. I tryied many times to do Adwords and Facebook Campaign but it's almost unsuccesfull. I pay almost 4$ per installation and it's too much for my budget.
