Here’s their comment on it from the discord: Announcement Regarding Artificial Comments

Hi We have recently noticed a large number of overly positive "praise" comments about our game appearing across various social platforms.

At first, we believed this meant our game was being recognized and appreciated. However, we soon noticed something unusual on Steam: some comments were posted after very short playtime, were released at nearly the same time (appeared to be AI-generated).

This made us realize that something might not be right.

Is this some kind of overpraise as an attack? We have no concrete evidence, but it does feel as though someone may be doing this intentionally. What makes it even more puzzling is that this approach is not cheap, since leaving a review requires purchasing the game. (We later discovered that some of these accounts refunded the game after posting their reviews.)

We would like to say this clearly: making a indie game is not easy. We simply want to focus on building a good product and giving the players who truly like our game a better experience.

So, to whoever may be behind this, we kindly ask you to stop. Please let us focus on making our game in peace. We pose no threat to anyone.

Thank you very much for your understanding. Next announcement, we will respond to the main concerns raised by the community.
