What it says above. Unlike in the Steam version, both shift keys and caps lock are broken. For example, left shift types 6 whenever I press it. Is anyone else experiencing this sort of behavior?

Have the same problem, Num Block does a "S" too XD weird bug, hope is fixed soon like the missing offline installers.

Other Keys like right control and AltGr actually type cyrillic letters.

On my Keyboard the F1-F12 Keys type capitalized roman Letters, also Keys like Home or Insert.
In the Config-file in the game files there are also some weird binding commands, so i don't know if it has anything to do with that or what those mean, might be worth to try out to remove them and start the game.

Maybe the dev send a sort of debug version to gog for release plus the already skuffed release for the game with no offline installers ?
