(The following is all on a bluetooth adapter - not the official Sony adapter - and not via wired USB.) Despite the game having graphics for DualShock button prompts, the left stick vertical axis of my DS4 did not function. Horizontal and X button was fine, strangely. Ended up using a third party tool to emulate an XInput controller, and that worked fine. Running on Windows 10. Does not function with Steam's controller wrapper, had to close Steam for controller to work at all. Score is preliminary, I've played for just under an hour and I'll probably enjoy it. Just wanted to get a bug warning out there quickly since this'll see increased traffic on sale. I did not test wired (which I think works as DInput), I saw one review reporting that DInput's broken too. TL;DR: Strangely incomplete, broken (at least bluetooth) DualShock 4 support
