There's a comment here saying that "The Actual Updated Version of this Game is here" with a link in the comment. Is this true? I feel like this shi is scam or something. And also, if the game did updated beyond of 4.2.2, do I have to re-download the game and redo my progress from zero?
Nope, don't trust any links posted by anyone with anything even remotely similar to "new update" in the comments - this is SCAM! I'm actively deleting those and banning accounts posting them, but they are many.
Dev will ALWAYS first create a post about the specified date when the update releases, then he will create another post with info that new version has been released and it will ONLY be available as download just above the comments section.
I, on the other hand, might post links redirecting you to our wiki page, hosted at miraheze.org, which can be trusted (I'm specified as a community moderator just above the downloads) and contain valuable info regarding the game itself.
Cheers
