Yes! I can turn into a dragon now!
This is aweso... Oh, wait, I can only fly for 20 seconds in a straight line before I hit the invisible wall at the map's edge. ... Oh, wait, I can't fly over mountains in the middle so I don't break triggers. ... Well, at least there's combat, now I can't wait to kick butt! ... Oh, wait, I can't move any farther than in my regular form. ... And I can't even one-shot these enemies ... and I'm taking a lot more damage than I was expecting.
why would i allow flight in a top down game? does not make too much sense IMO. the point of flying is moving in 3D after all
