I opened it in Ubuntu(Kubuntu) but Play and Quit button is not doing anything.
Hey, thanks for trying it out!
Could you elaborate on what you're pressing, and whether you're using a controller? I can use arrow keys and spacebar to interact with the buttons fine in a Kubuntu VM.
I have Alienware 15 R3(1980x1080 screen) and I'm using the built-in keyboard. I can able to navigate up and down(play and quit) but can't select it. For selecting I tried "Enter Key" and "Left Mouse Button". And tried pressing all the alphabet keys.
