I am very interested in doing this project for you! I am experienced with Game Maker: Studio, you may have heard of it? It is perfect software for a 2d game like Bubble Shooter. It's very flexible software, and can deliver just the game you want. It can export to Android format. I am more than happy to discuss this further over chat, and can also prototype some of the game for free if that works for you? Just so you can know you'll be happy with it. I really hope to hear from you soon. Feel free to message me if you have any questions.
