A really unique and potential-packed premise that is sadly wasted and not acted upon.
The game is only a handful of hours long and it feels like a chore all the way through. The combat system is an incredibly tedious system where you can add either positive or negative status effects depending on how you want the fight to go. It's unique at first, but you realize pretty quickly that getting anything done for most of the game will rely upon you passively casting spells and waiting for a fight to clear out by itself, or if you want sex to happen, you have to wait for an enemy to begin sex and keep on passing turns as the hero keeps pushing away until you finally arrive at the static image of the sex. I can't really get invested in the erotica with a system as tedious as this.
The game advertises itself as you playing as the corrupter, i.e the demon lord reincarnated as a suit of armor that a hero wears which you can then slowly influence to have sex with monsters.
Being the personal equipment of a hero and having a subtle sway over how things occur to corrupt them is such unique premise with so many cool ways it could branch out. There's strong comedy with the armor the demon king resides in being personified with cartoon eyes, whilst the demon lord can only whinge about his lack of direct autonomy. Or how the kingdom theorizes about the demon king's presence, right in front of the armor the demon king has taken control over.
The sad thing? This NEVER matters.
You are instead a vessel in which the hero has sex through. Other monsters can have sex with the hero which you can influence to happen, but the only thing you do get is near the start where the armor you're in can grow tentacles and slowly grope the hero while they sleep, that's it. Your level does not matter, your degree of influence will stay the exact place as it was at the start of the game. The hero will always just orgasm, get embarrassed, or get pregnant, that's how far the "Corruption" in this game goes. No mental changes, no transformations, no sense of anything changing. This could have just been a standard rpg where you can get fucked by monsters and very little would have to change.
As for what does get involved in the sex scenes? You encounter enemies that are 95% animals, I'm not completely against the idea but there is no. flavor. Octopus, worms, leeches that can sting you and arouse you while untreated, slugs that can invade you and arouse you while untreated, cliche human perverts, bugs, and some more bugs. You enter an area with ghosts but all they ever do is just dick you down like everything else.
A demon attack occurs in one of the places you go to, you think you can encounter demons that the hero can bang? No. There's just dogs, why are dogs placed there!? This is a game about demons let me get fucked by demons. The actual (rather good-looking) demons you can fight? They are boss fights that never start sex scenes and if you're beaten by them, your reward is a game over screen, that's it.
The game has so much charm with its characters (A twist happens with two characters I was genuinely surprised at, and your inventor friend's casual attitude towards mass destruction is hilarious ), but I don't know, if you're really into monster sex, i guess you can try this one, but it doesn't do that much man.
