Thank you so much for the feedback!
Yes, right now i'm working on Key binding and Joystick support, you probably could try it here first in the next update soon... even before Steam release :)
And also noted for multiplayer player mode.
cool. I use PS4 controllers through steam typically. I tried mapping through it natively and through the steam big picture mode and wasn't able to get it working at all which was a shame. I also quit the application, tried to play it again and the launcher somehow deleted itself. Don't know why that would have happened. My antivirus didn't pop up anything letting me know.
