Steam Deck mouse region aiming Steam Deck about 3 hours
combined playtime Disable gamepad in noita's input options. Use right trackpad for aiming, it's almost as good as a mouse and way better than stick aiming. Triggers are left and right mouse buttons. Controller works as a keyboard. Big thanks to DoubleJumpPunch for the baseline, although the values needed some tweaking.
