After touching a total past 100 games, I can confidently say that this is my pick for Top Prize. While not an artistic masterpiece, this game still rings the most in my memory as the most painful experience that I successfully endured. In a way, this game had a little luck on its side because as I played more and more games, the novelty of the concept was quickly wearing off.
You've done very well. Perhaps this style of game is something you should revisit and refine.
