Explanation

Right mouse button not working on Fedora Linux in the demo. Middle mouse also not working. WASD works for camera movement.

Draggings belts also does not work, only single clicking is working. Mouse and keyboard work fine in all of the other games on Steam, as well as my OS - i tested that.

I have no gamepads attached - someone on Steam forums metioned that unplugging a controller and testing again might help.

Also, dragging a module 1 from the assembler into the right works, dragging the second item from left to right does not work, the mouse "un-grabs" the item quickly. Holding left-click holds item 2 in the air, but then moving the mouse drops the item immediately...

Switching to Proton version GE-Proton12-26 (not the lastest, but it is what i had installed) made the mouse issues go away. Now the game is running smoothly!
