It's the only way I've ever known for this game. I tried controller once to help someone beat a dungeon but I kept on messing up. Didn't know what what on what. I knew how to switch to different sub button but I couldn't remember which action was on what sub layer. And I had difficulty targeting. I do like being able to click on my target instead of cycling through all possible targets. One thing I did notice is that with controllers, you can get through window pop-ups faster, (ie. Open the door?, use the card? Start the elevator?).
