Hey all, anyone else having trouble getting their controller working? I've seen fixes to get it working on Steam, but... uh... this ain't Steam. Anyone got a fix for getting their controller working for a GOG version?

Not an ideal solution, but it worked. Thanks.

I'm glad you solved this but just for others who may stroll in here I am using a 360 controller plug and play. (Actually off brand)

I am using DualShock 4, so as with every single non-Steam game, also with this game I have to use DS4Win. Officially Steam does not really support DS4 either, because Sony only allows the use on Playstation 4, but their support/FAQ states something like:

DualShock 4 may or may not work, but we cannot guarantee it because it is Sony proprietary device, but you can try. ;)

On Steam it works plug and play, though. But every other game, everywhere else, I have to use DS4Win. I pinned the shortcut so it's actually not a big deal to just click the icon before playing a non-Steam game.

Just have to remember that:
X = A
○ = B
□ = X
▲ = Y

But I don't look at my fingers while playing anyway.
