Maybe it's just a personal skill issue, but I find it hard to use the map on mobile (Android) - sometimes I have to tap a whole cm or so to the right side of where I want to go. By sliding with the finger I can move the mous over a destination, but do I have tap again on whereever my finger is when reaching said destination, or on the destination itself? Both ways seem to (not) work...
EDIT: Oh and... Thank you for making this. It's an incredible game^^
