The game has some controller support, mainly ballrace and just walking around places, but Unreal Engine doesn't have it's own menu navigation thingy for controllers, so it's waaaaaaay on hold.
At least that's what I remember, it was something mac said in the discord more than a year ago, I don't remember if that's it exactly.
I really want controller support. I really do. It makes everything easier and I feel like I have a bit more control over where I go and what I do, and reflexes. It already makes a massive difference in ballrace.
