There seems to be no controller support even though Heist 1 does have it, and also it seems to be supported in the steam version. Can this be fixed in a future update?

Are you basing that on the GOG store page or did you try it with a controller?

I tried it on Winlator (windows emulator for android) and nether the virtual gamepad nor bluetooth dualsense were detected. Even though they work flawlessly for Heist 1 and LOK: Defiance. The store page was just a confirmation.
Does it work for you? What windows are you using? Maybe it's related to the windows version

Gotcha. I don't usually play with a controller, but if I'm able to test it out at some point I'll post an update here.

Thanks in advance!

Update:

Actually DualSense works flawlessly on Windows.
Also got it to work on linux/wine.
It seams to be Winlator related, but I still have some ideas.
