Not really, as this was a pretty innovative game that did something other games had never done before. There are some good corruption games out there, like
Third Crisis,
Magical Girl Celesphonia,
Detective of Steam City,
Liz and the tower grimoire,
Succulence and
Claires Quest all being pretty good imo. Though they are just above standard RPGM (bar Third Crisis, that one is Unity engine) games, while they all have some innovative stuff, none are really like KP.
Try using the search feature for the tags "corruption" and "RPGM" as engine and you may find something that is your specific style.
Not all bad news though, as this game will be updated around winter/spring with a new side-job, and when that happens, it (probably) means we will finally get an update to the main mod of the game, opening up a lot more potential, things to do, and ways to play this game, without it being scuffed.
