Really fantastic game. Already worth to ask for money with the next update if you ask me. Paid more for less on this side a few times
Little feedback from me if i may:
Its unclear that you need to bring the screwdriver back to the spawn to access the second level.
Tried half an hour to find a knife or scissors to cut the tape of the vent beside the door in the robotic lab since you can loose the screws. This seemed to be the logical exit in my head.
Inside the second character its unclear if that is full tour or an endless loop. I let myself squeeze myself along her/his intestines because its unbeleavable awesome but pressed r after half an hour, figured it must be a loop. (full tour here please! :D)
I really really love the seamless transitions from outside the bodies to inside them and the interactions and comments. (This is how vore should be for me)
Hope for AV next / all Options for all of them to have choices.
8/10 for that demo from me so far.
