Hello there! My name is Sunil and I am excited to let you know that I have a solid background in both Android game design and development, making me the perfect person for your mobile game project. From your description and attached videos, I can see that you're looking for a game similar to Clash Royal, incorporating unique ideas such as special abilities for main tower characters. I can assure you that not only do I understand this genre well, but I've also implemented innovative features in past projects.
Having been in the field for a while now, I am not just up to date with the latest industry trends and tools - but also understand what makes a game truly engaging and addictive. For your desired 60 cards and 12 main tower cards, as well as online multiplayer PVP matches with diverse maps, I am comfortable working on such scaling projects.
Moreover, my skillset also extends to website development and management which could be a valuable bonus when it comes to integrating in-app purchases(IAP), ads for cards and spinning wheel elements. With me, you will have an expert who is mindful of timeframes, budgets and believes in open communication throughout the project. So let's team up now and create an outstanding mobile game - one that surpasses your previous experience while echoing the essence of Clash Royal!
