Hi there,
Quick little change I'd like to see. Make the Harpy Lair fit on the watery spot tile found in the Rock Coast.
The Harpy lair is 1 tile too big for the watery spot and it's perfect to give a level some constant harassment which can't be stopped without some flyers.
Screenshot for reference and I've highlighted the one rogue tile which prevents it being put on here. You could actually change the southern part of the watery spot too to fit it.
