Love to see different games represented!
I don't know why, but i find the idea of the game absolutely hilarious. I can honestly say I've never played another game where I throw chalk at students :D
I think the main thing I would adjust with the game is increase how fast it scales, it felt like I could go on forever if I played it well. Also if hitting a chalk didn't increase order, it would also help with the same issue.
Overall excellent job executing on a simple yet really unique and interesting idea!
