The file was quarantined for about a day. You can still download the game, but there was a warning on it. It's gone now, I think.
Itch quarantines files sometimes if they feel something's off, like if a dead account suddenly posts game updates, if the dev's from a no-no place (Russia's the big one, IIRC), or if a brand new account starts dropping download links for their new game with no warning.
Unrelated side note: saw someone else say it, but yeah, it looks like the download is for 1.0, not 1.0.1. You updated the browser version but the downloadable one is still marked as being 1.0.
