Sorry to revive this old thread, but I'm having a similar issue. I'm trying to use a PowerA Enhanced Wired Controller for Nintendo Switch. The game reads A as X, Y as A and X as Y, despite no other games doing so. Running the game through Steam with Steam Input enabled fixed the button mappings, but didn't fix the aiming issue. I cannot aim to the sides, just up and down, though interestingly, I don't need to press any buttons to turn around, I just move the right stick.
