Are you downloading the game from the official game page?
I downloaded it here from itch, using the download button on top of this comments section (as mentioned, I got the version labled as 0.9.0). If there is another 'official page' then I would not know about it.
Now... this game looks very interesting, and I want to check it out (obviously), but I would hate to infect my system, if that didn't already happen.
