Hey man! Cool idea!
It took me a little while to work out what I was meant to do first. Maybe a brief pause at the beginning to give people a chance to see what's going on without worrying about placing pieces would be helpful?
That said, the game was nice and easy. With just enough stress waiting for the piece you need while making a mess of the map with all the extras I had, and worrying about making sure I didn't dump things somewhere that would mess me up next time!
