Glad you enjoyed it!
I'm currently working through a couple different ideas for how N-Gons are awarded and one of the concepts I'm leaning towards involves variable rewards. Speed and less moves would be the determining factors, most likely.
It is definitely an opportunity for juice! I've already begun to come up with a shiney look for the N-Gon "icon". Can't wait to get into more graphical polish in the coming months!
Thanks for the comments, Nick!
