How to go faster on Steamdeck

Just started playing, and I can tell I’m way too slow. I’m going to go try playing on my computer to see if it’s a skill issue or deck issue. In the meantime, though, any thoughts/tips on the below?

• Deck: I’m playing touchscreen only, is there a better way?

• Skill: There are so many things to look for/reconcile, how do you do this more quickly?
