Ah yes, there's that. Lots of running to get anywhere. They need to either allow fast travel points to be used directly by clicking the map (instead of being forced to walk all the way to the closest one), or make running faster.
The map is quite big (which again, is amazing and well done for a smut game), running around to fuck things (either figuratively or literally speaking) makes it very boring after the first few quests, because you know you'll be holding that shift key for a entire min or two to get to the next waypoint (which also makes me think they should make the sprint a toggle instead of a hold key action, but details...).
I imagine they plan to mitigate this by adding side content on map, which would then make taking time to get anywhere actually interesting, since you would randomly find things to do along the way (kinda what Witcher 3 for example does).
Anyway, the potential is there, and they seem to be going in the right direction so far. Let's see how the game shapes up in the future if they keep the good work.
To be fair, the little content it has it's very well done. Comparing to the endless sea of shitty slapped togheter trash that are most adult/smut games. I would put this project in the same level of quality of
Fallen Doll,
Wild Life and
Breeders of the Nephelym, except Carnal Instinct has actual good gameplay/combat, and gigantic cocks, so we could actually destroy holes.
Even the performance is not the common "your PC fans will become fighter jets with afterburners on" most Unreal and Unity 3D projects are. But they do need to optimize heavily performance later, which will and should only become a true aim after there is content I think.
