Very late, but I played this game through and it was a lot of fun. I would definitely have it expanded if that decision were up to me.
In terms of content within the existing game, it would be fun to be allowed to play with the subject that gets permanently caught in the turbine (or whatever that spinny thing is). As it currently stands, they just lay there on the ground hornily forever... some form of interaction would be a welcome addition, perhaps with the excuse of "investigating" the monstrous thing for useful info.
It would also be a lot of fun if we could either do more things to the sealed doctor, or if there were more obvious feedback from her when we tease her, perhaps an escalating series of reactions from her as we continue delivering secondhand justice to the worst personality in the lab.
Of course, as this was made a long time ago, I don't expect this to even reach you, the developer. But if it does, hey, thanks for making this game, it gave me a happy few days of playing around.
