Thank you for the feedback! Unfortunately I'm not sure how to make the dualshock support work as seamlessly as on steam, seems like it handles that better there due to its api. I used ds4windows when testing the game myself.
I'll be honest, I totally forgot ds4windows even existed, it'd been so long since I had ever thought about it with pretty much every game aside from a few smaller indie titles had worked regardless, I thought there was some kind of breakthrough that I didn't hear about or something. Good reminder that it exists still!
All that aside, still a lovely demo, I'll be playing until I can comfortably 1cc the whole stage haha
