Touchscreens do seem like the most natural way to play this game I've seen. It's just taking out unnecessary instruments from the way of playing game. No need to learn how to control a mouse/pencil to aim when you can do it with your fingers most of us are already pretty good at moving around. If it makes the maps too easy, it is a problem with maps and there should be harder maps that are enjoyable and give a challenge to play.
For a game that's based on point and click on a 2d static plane, I don't see any problem in using a 2d plane you can click on to play.
PP/rankings are secondary in this game imo, something that will adjust to how people choose to play this game, not the other way around.
To make touchscreen a more viable playstyle, i think you would need to add a way to enable tapping with one hand (tapping the touchscreen like you would a keyboard/mouse and register the hits as m1/m2). For example: If you'd hold a finger down on the touchscreen, your taps with other hand could register as m1/k2 for doing streams (cursor follows the finger pressed down).
For ranking/pp, i feel differend ways of playing are not equal. It's like weight classes in boxing. I don't really care about it tho, this is a solo "sport" mainly.
