I enjoyed playing!! Always happy playing a chess game! The only thing I found frustrating is when I made a mistake I wanted to see if there was a restart level option (while keeping the time). I pressed the menu, as it was my only button, then lost all my progress. Also, it would have been nice to have a visual indicator of the moving piece. I know you can figure it out by switching pieces; however, a little visual icon wouldn't help! Very impressive for 5 days of work!
