The port was not made by me, I only do the PC versions.
So updates for the console version are for Top Hat Studios.
Sadly, they stopped doing updates because it's too expensive on their side. And because the game was originally created in Unity 5 the upgrade to a newer Unity broke many things and it was a real challenge for them to get it running on consoles. So the controls/input system is not perfect. So I'm sad to say that there won't be any updates with dpad support unless Top Hat changes their mind and give it another shot. But I think they gave up after many attempts to implement it.
The next game, Alisa - The Parting, will definitely support dpad since I'm already using a newer version of Unity and rewrote almost everything so it'll be 100% compatible.
But I can't do this for the old Alisa game, that would take many months of work.
