have you tried installing through the itch app? let us know, if you’re having issues installing through the app we’ll take a closer look.
Installing through the app sort of works -- the game starts up, and I see some vertical black pillars against a purple sky. There is a gray cube. No cursor. Mouse doesn't seem to do anything. Escape gives me a screen labeled "discone" with a quote from the narrator, and a settings button which does nothing when I click on it. Escape again takes me back to the pillars. Keys other than escape do nothing.
