I started the game trhought he itch launcer, which i launch through steam to allow ps4 controller input in all itch games.
For some reason all input are mapped to the right annalog stick. Gently tapping it in any dirrection causes all sort of things to happen on repeat. The pause menu rappidly opens and closes, the camera swings aroud, the character performs all kind of moves in rappid succesion.
Turning on old controls, allows me to control the camera with the left annalog stick. But not much else.
