By far, no bugs on my playthrough, even came across multiple female versions of the coilhead. Still very early in the games stages, you plan on adding anything new for the next update, whether it will be lewd or concern gameplay?
I also noticed the player character being male which is fine, but will a female player also be playable in this game by any chance? Even though that means extra work for animations and such.
Extra:
Animations:
Plus I also noticed in the description you will include fetishes, great but I don't know if impregnation may work here even with a female player character which is my main fetish although it may work, up to you, I know its not everyones thing, oh and lactation. I would say for enemies if you need ideas, you know about the "Masked" entity in LC? If so then you'd know that anyone who puts on that mask for too long get corrupted, I was thinking of maybe allowing other "lost" spelunkers (human NPCS) wear these masks prowl the houses looking for you.
I have more things to say but I don't know how far you're willing to go with different sexual topics.
Although I think this game would do well with more visual cum. For example have the penis covered in cum after they creampied a creature if they still keep having sex with it that is until they stop then its cleaned.
Struggle mechanic?:
Give the enemies unlimited stamina during intercourse. Allow the player to struggle out of grasps or intercourse against the creatures or some, include a skill check of some kind to help the player escape the grasp and if they fail the check, a good portion of the purple bar will be filled unless the player wants to give in completely.
Excuse me for all this writing, I know you're just starting off. But I do believe you may get some idea out of this comment. Even if it doesn't, you could clue me in on what may come next update.
