I think there is a very frustrating, game-breaking bug on mac. We got to a point where it showed 7 shapes in a row onscreen, and there were 3 more off-screen to the right. The first two were not selectable, and the ones that were selectable were selected out of order. They were rearrangeable, like section 2. There were duplicates of the same shape. Couldn't find an input that worked.
The malware input also didn't work, so I don't think it was the ending. It was very frustrating, since the nature of the game makes it unclear if this was an intentional "glitch" or a real bug, so we banged our collective head against the wall for a long time and eventually gave up. I retried on windows and had no issues, so I don't think it was intentional. Has anyone else encountered this?
