Excited for the next level update!
Also, does anyone know JAVs, or other videos that have the same corruption dynamic?
You mean games, not videos?
The corruption genre is basically a standard in most games featuring female protagonist, but in my opinion no game does it better than Karryn's Prison. In most H-RPGMs, the dungeon crawl portion of the game is somewhat detached from the corruption quests and jobs, with the only connector being money earned from lewd activities that the player may spend on better fighting/magic equipment and that's it.
One such example is 'Kozue's strange journey' where the main character, a typical innocent schoolgirl discovers another world full of monsters and has to defeat them stage by stage within allotted time. The gmae world is actually divided into the real world and the other world, which you may access through several portals. You as the player are to discover that she may earn some money by letting an old man see her panties in the park and it progresses from there, including some undeniably incestuous themes... which have nothing to do with her progress in the otherworld dungeons. In result, the game feels kinda sorta like your ordinary Zelda's clone spiced up with disconnected H-scenes.
Then there is 'Ambrosia' which I am soon going to finish playing. This one has a better handle of the corruption theme than 'Kozue', but it feels rushed in the end and not well planned out, with a lot of side quest that you may easily miss and then discover once your heroine is a full-blown skank, seasoned whore, stripper and corrupted priestess in one, to be rewarded with relatively mild H-scenes that would make sense at the early stages of the game, not when her lewdness meter hit 999 many days ago. And yeah, it seems like a high number and a lot of grind to achieve, but after reaching 250 on that gauge nothing changes really. The H-scenes soon become boring and repetitive, with not a lot of choices available.
In 'Karryn's Prison' her actual sluttery becomes weaponized to devastating effect. Of course there are other games where sexual encounters are depicted as 'battles' and you may inflict 'lust damage' instead of physical or magical but I don't think that anyone has ever done it in such an engaging, almost perfectly balanced manner that makes much more sense than adventures of yet another princess looking for yet another treasure and getting raped by mushroom-highwaymen as she ventures further and further... until she finally admits she loves all the abuse and never wanted to find the goddamn treasure in the first place.
