This surely seems to be a hidden gem. Renders aren't flashy but the overall experience is very worth (I'm all for mindfvk stories- and a cheerleader that's the polar opposite of a diva/queen b? That's actually innovative).
Regarding the lava-hot burning topic (you know, the one that starts with n- and ends in -tr),well, imho, I can see why people want to avoid it (especially in situations where you really get attached with the characters) but like some others said, it can perfectly fit into the story if done right;and in a game that reeks of covert ops and espionage
where literally every girl you meet can be an enemy agent apparently there aren't many things that come to mind where it could be more fitting (plus, for example the girl doing it could very well be acting in order to earn trust and extract information but the mc wouldn't know that; so, it would be like Schrodinger's ntr).
Regardless, hope it turns out as the dev would like
