The application does not start. Steam shows it to be "Running", there are two processes in the background... but nothing happens. I tried restarting the computer, I uninstalled and reinstalled - no change. I checked for any logfiles in the folder, but could not find any. OS is Windows 10, 8 GB RAM. Is there anyone else with this problem?...

The numbers, - (for negative), and the decimal point on the number-pad on the keyboard work, but there is no button for the Devil key. This seriously ruins the possibility for immersion and leaves me clicking away with the mouse, which is totally sad. You don't use the addition key for anything and it's typically large, it should be the Devil Key, or hotkeyable to the Devil Key. Is there any key at all assigned to the Devil key as a hotkey? Something I can rebind to + while playing?...

Instructions in Tools say to hold +/- and the special keys to toggle SFX and get more info respectively, but holding them doesn't seem to do anything. Am I missing something? Do I need to be in a very specific, unspecified context? It doesn't work either in Tools or the game proper....

The gam's description mentions a demo, but I'm not seeing a "Download Demo" button on the store page. Is the demo only available outside of Steam?

When I open the game from Steam, on OSX 10.15.7, I get a popup saying that the app encountered a problem. Any advice?
