what the genuine fuck is this game?
Heal Slutting refers to the sexual fetish of being the designated submissive healer of a group. Originally it started as a shit post on 4chan but some people realized they actually liked it and the OW came out and some website published an article about it and the whole thing exploded in popularity. Today there's a subreddit devoted to it, at least a few discords that I'm aware of and a semi-regular thread on /trash/. They're horny dorks, to be brief.
Healslut is a visual novel about a shut in nerd who's testing a new age VR RPG and due to a glitch is forced into playing the 'heal slut' class on their first run. Also injects some high concept science fiction and a dash of comedy.
I will wait for a couple more updates because I feel at some point the story began to be less fleshed out compared to the beginning.
Classic bloat syndrome. When the game only really had a single story arc to follow with limited branching options it got a lot more attention and care than when it split out into ~4 meaningfully different arcs. Not even a mark against the game, but this is why pre-planning is so important in game development.
