Steamdeck Bliss!

Base controller layout is mostly stock but with some sane back button mappings so you mostly keep your thumbs on the sticks. I did change left stick to wasd, and right stick to a highly tuned mouse control. These changes give faster and mor presice control, while also avoiding some weirdness with the default sticks. I also spent a lot of time tuning the gyro for precise aim assistance, but you can easily disable it if you want.
