The linux version won't work on 64-bit versions of linux.  Please post a 64-bit version without 32-bit dependencies to install (like some games do) or post a version that has both 32 and 64 bit binaries (in a zip file without the need to install, similar to what you did for the 32-bit version).

Hey, sorry the game isn't running on your system. I created a very quick new branch of Milkmaid and have exported a Linux x86_64 build that should be available now.

Warning: I don't have a Linux system and have little to no experience with it, so it's not been tested. But if it runs, you've got the latest and greatest version of Milkmaid available (barring the Switch version) :)

That worked on 64-b it Debian 9.2.  The only issue I found was that the game seems to refer to controller inputs (A button, B button, etc), but the game doesn't recognize input from my xbox 360 controller.  I was able to use the mouse though.

If possible, it would be nice to be able to turn off the inventory bar at the bottom of the screen most of the time unless the player pushes an inventory button (for example, the right mouse button) or hovers the mouse at the bottom of the screen.  Having it visible almost constantly confused me for a while and I spent far to long feeling like something was wrong and trying to turn it off.

Ah, there are probably some leftover button references since this version is basically a port of the Switch version. I hear you about the inventory bar, but I don't have the time to do any changes to UI for now. Glad that it worked though! :)
