The game will get an update one day, but honestly... its one of my favorites already.
My biggest issue is how insanely hard the ending is, even with lots of blessings, since you have to fight your own teammates (who may have really good weapons or spells) and after that fight, lots of very tough foes show up and it gets very messy.
Aside from that, I just really like how that game deals with the combat/porn mechanics. A character will be incapacitated when grabed and her clothing slowly removed, but she can be rescued by her teammates or struggle on her own if she has the energy for it, no game over if a character has no hp left, in fact you can rescue them and they'll fight again, only when your 3 characters are on the ground and done for you get a game over. A character with 0 hp will also keep getting fucked until rescued, so you can just let her like that to enjoy the show.
Lots of tiny touches too, like one of the succubus that does a mating press will start wiggling her dick if the character she is fucking has low corruption/hornyness. or that there is a teleporter you can take, but if the girl that gets separated gets brought to 0 and fucked, you can just....leaver her here, lol, move on to the next stage and you get one less teammate.
