Hi dev
First of all, the technical demo is interesting on many points. Graphics are really well made, plus the animations, may them be on the scenes or on the "shoot" are well done too.
As I can see, there is a lot of work to do, may that be on graphical stuff to add, story (I suppose you'll add one eventually) etc.
So here I have some suggestions for you, considering some other game of the like that are to actually in developpement with interesting mechanics.
Animations
-Scenes
For the scenes, as Bioasshard did it, having some variables to pick on different scenes available, unlocking depending on the variables and blocking some, even pumping the probability to have some is a pretty nice idea.
A little list of the variables you may find usefull in the future :
Enemy Position from X (X means Character) : Front, behind, sides, even top, or under (Depending on what you're planning, I suppose some could even be waiting hidden under a thin layer of ground, or some trying to jump on X).
X's position - Standing, crouching, lying, sitting (depending on the amount of position interaction you plan to add ofc).
X's emplacement - Empty space, Next to a wall like surface, next to an elevated like surface (bench / car).. - Next to a wall with a big hole like surface on ground level, under world items - Next to a wall with a big hole like surface on body level
-Number of enemies with enemy types
Mechanics
Scenes
- X's mental / psychology's modification (changing what X says during scenes + resistance, even changing resistance to acceptance at some point, which could impact the RNG depending on the enemy)
- X's attributes (RNG based i.e, bound to mental's and psychology's modification, but once reached, couldn't be back from) - Vaginal / anal / bucal's attributes, like width, sensitivity
Creature's affinity (modifying gameplay, like runing slower, being less able to shoot right, even not being able to shot at some point, being not able to move at some point). Those attributes, depending on the level could unlock some stuffs, like scenes variations, specific outfits that unlock more specifics scenes for specifics enemies, while modifying the behaviour of most the the enemies we could encounter.
Drugs (amplifying sensitivity, sexdrive, could also make her "addict", which could lead to some maluses if addiction not met while being addict, having a way to remove the addiction)
- Creatures before / after scene RNG
Rerape RNG (Risk of being taken multiple times in a row)
Forced Drugs (tentacles using some kind of slime, humanoids using siringe)
Get Caught (being napped by an enemy, taken into a hive and having to struggle to get out, specific dialogues, some kind of activities to comply with) -
Script
It would be also interesting to have scenario / script variation depending on variables, if you do not implant a psychology modification like mechanic, having the character say something different the more she's taken, depending on the enemy who's taking her could be pretty immersive to.
Plus, having the character saying things before the scene will start, which let us hear the thing slipping to the bad point for her. That would somehow need some transitions between positions, and between the grabs and the first position during which dialogue should be displayed.
Like when seeing a tentacle she could say smth like :"What the hell is that" "How disgusting" ... some sort of stuff like
Let me know if you plan to add some stuff like the ones I wrote in the post.
Keep up the good work
