Is that… comfortable? That sounds like a really awkward way to play.
It was kinda OK. It actually had the benefit of analog movement as compared to WASD. Biggest downside was the small screen.
Any reason you didn’t do all in on the controller or keyboard+mouse?
The game did not seem to work with controller only and forced me to use the trackpads and I cannot play FPS games with just a controller anyway. As for why no keyboard, the answer is simple: I was too lazy to get up and get my BT keyboard and my USB C dock (all my Deck accessories are stored in a dedicated bag).
