for the bondage piston: i just check the game and yes the machine is there, i just a bit lazy to upgrade the bar 😋😋😋.
for the update version: I rarely update my games so i don't know how many updates i have missed, sorry.
for the demo: i agree with you, it the bought version has more story compare to the demo version but hey! i got the bondage piston there, so i won't complain here.
also, because i haven't update my game yet, I'm going have to be careful about this. i don't now if you already patch this but during the mission to search of the sheep fapet recipe i need to find two things which is the recipe for the fapet and a double dildo. the hint said "i left the other one on one of the hill around here" and the light shone on one of the hill in front of nishy. I'm not sure if i describe it correctly, but i will send you the photo as soon as i unlock the theatre.
