it this game worth playing? or I should wait more?
It is worth playing, but you need to be aware Karryn´s Prison is not a fap to go game.
You will not download it give it two to three hours fap once and deinstall it.
That is not the idea from the developer.
KP is more a gindy strategy game, you have to invest time to understand the game mechanic and you need to plan ahead.
For the CG´s Blowjob, Handjob, Rimjob, Titfuck, Anal, Vaginal, Footjob and Toys.
Humans (all forms and shapes), Orcs, Slime, Goblin, Lizardman.
You have various positions with different enemys, not seeing the same CG over and over again.
You have side jobs that have their own CG and every lvl has his own defeat scene. (It is not a game over rage game)
So if you ask is it worth a shot, absolutely. It will suck up a lot of time and you need to play it seriously.
Right now you can´t beat the game, you can subjugate the first and second floor. But that is far then enough.
If you search for short fap material, KP is not your game.
