I did it! INLCUDING THE LAST LEVEL! It was pretty satisfying to play, a good sense of "planning" followed by "cross your fingers and hope it all works how you imagined it"! I think it can cause a slight negative player feeling when you plan you 6+ fans, and then realise your first 1 or 2 was problematic so you don't get very far. However, if you could keep previously placed fans, I think it'd take away from some of the games charm - so I'm not sure the right solution there! Thanks for letting us enjoy your game <3
