My 2 cents about the game (0.12).
1. Currently you can use any H-move (grope/masturbate/sex) on your opponent from the start. And after you've seen them all you kinda lose interest in the game.
Advice: add independent corruption stats (experience/levels) for the character. Allow only simple groping from the start (level 1). Add corruption experience for using H-moves on your opponents. Levelling up in corruption should allow the usage of more hardcore H-moves. Alternatively you can grant new corruption levels after winning specific fights with "story" characters.
2. I've seen that after you use a H-move on your opponent your opponent may overpower you and use a H-move on you instead.
Not sure how this is implemented currently (a specific skill that activates at certain moments?) but some interesting mechanic can definitely be used here. E.g. while your opponent performs a H-move on your character you can mash some button(s) and based on some stats (STR + WIL + arousal of your opponent vs STR + CHA of your character) you may or may not be able to fill some progress bar and overpower your opponent and use a H-move on him/her instead of trying to escape. Perhaps it's already implemented in a way but I haven't seen an option to gain this overpowering skill yet.
3. The finishing/orgasm animations look ridiculously jerky which ruins the impression of the game.
Advice: either make them more realistic yourself or add an option to export/import specific animations (and some how-to guide ofc) so that the community could fix them for you or even add some new ones.
4. The voice volume is too low compared to sfx volume (e.g. clothes' tearing).
Solution: normalize all sound files or add separate sliders for sfx and voice.
Also, I understand that this is a single-dev-made game and not an AAA project but when a single player game has one single trivial type of gameplay (1 on 1 battle) regardless of how many animations it has (unless they're professionally made) it'll get boring fast, i.e. the replayability of the game will be very low and fewer and fewer people will support it over time.
enlit3d already has another game (CATC) where he more or less implemented a dungeon crawler with a turn-based combat. Add to that 1 on 1 battles from HR2 on some sort of an arena and some kind of brothel management simulator and we'll get several elements of gameplay in one game (SimBro3D lol) with high reuse of models and animations and high replayability due to many paths that you can take in managing this brothel.
Yes I'm suggesting combining CATC with HR2 with a brothel simulator in a new game.
