If I had it to do again, I'd add a way of jumping straight to the game. It was all a bit of a rush, to be honest..!
It may not be evident, but the Mage hides in a randomly different spot each time, so it can be played more than once. He's visible, unless, unattended, a Knight approaches, in which case he becomes invisible (he's a Mage, after all..!). Once found, he can no longer do this, so it's necessary to avoid being seen when returning to the start point.
Thanks for playing, and the comments. Have a great day.
