Joni Mikkola is currently working on his next mobile game in Northern Finland. He keeps his game developing stamina up to the mark by training regularly at the gym and eating healthy. While developing games, he often reads books, plays the piano, or bakes buns to keep ideas flowing and his mind focused. He is constantly challenging the status quo, which in turn helps him learn new ways to create things.

He has developed games for over 4 years professionally, mostly for mobile platforms. He targets casual games and focuses on creating simplistic designs. With one game released, he is currently working on his next game, which will be released in late 2015 for the Android and iOS platforms.
