Hi, I submitted my first game to the Windows Store today. It was more the curiosity of programming a game and releasing it which drove me to do it, but I also integrated some advertising. I will also attempt an iOS conversion.
The game itself turned out quite well. It is a twist on combining gems where you have to spin a board and catch incoming gems from all sides to into the right spot to combine them. As the board gets bigger and you have to combine up to 27 gems to get to the highest gem level it can become also pretty fast

Please give it a “spin” and let me know what you think.
