To clear any confusion, the games shows very slow or barely any development not hecause of abandonment, but because the dev (Licenciado Samuel) isn't showing much progress with the game, so it's in some sort of a limp mode at the current state, and the team that was helping the dev to create and continue updating this game has left the dev to focus on a different project, or at least that's what I understood from the poorly translated Spanish from the official discord server of this game (poorly translated as in i translated it with Google translate not that the team had a bad translation or anything)
I am also quite sad to hear that this game will probably not get updated anymore, considering I grew quite fond of this story, but I guess good things go away quicker than expected (I especially hate the fact that I started loving the story the most right when it ended)
But please don't believe everything ive just said, im not a dev nor part of the team that made this game, but I see a lot of activity for this game and confusion about this games progress and I wanted to make it clear for everybody, and im not saying to stop supporting the dev or the game, I actually encourage it, cuz maybe then they'll actually start being more active and restart development for this game, but nobody can confirm this, I just hope (like many other people do) that the dev comes back and continues development for this game.
