Ah, thanks for making a thread about this. I'm surprised it hasn't gotten a ton of attention yet - the game is truly incredible. There's a free version somewhere, but it's not nearly as good as the remake (this one), and has much less content.
I would definitely say that this is one of the best indie RPGMaker games I've seen in a year. I would say years, but Undertale exists, and while looked down upon, (and not even from RPGMaker!), I still believe that it was a decent game for what it was.
For sure one of those games that you pick up from nowhere and find great enjoyment with. I did, at least, and the meta stuff doesn't get too edgy. Hope everyone who tries it likes it as much as I did!
