Do not forget that this is a first version of the game, changes can be made later if criticism is constructive.
I find, for my part, illogical that there is a direct game over in this game when you lose a fight. As said above, we can see a girl getting fucked by a zombie and in the end she likes that. It does not seem to kill her.
When you lose a fight, Jane is fucked, the zombie goes away when he finishes without hurting her in any way. And we finish with the sentence that says Jane is lying on the floor and leaving there. Then ... Game Over ... Oo
So she was badly fucked and she did not like that and that's why we have a Game Over?
I find that there is something to be done there, for example adding a stat of corruption that would increase each time she gets fucked by a zombie. It would increase slowly if it follows a mandatory scene in history, and it would increase faster if it suffered as a defeat in a fight.
It would be possible to reduce this corruption by swallowing a special pill or by disinfecting.
But when the corruption reaches the max level, it leads to an automatic scene where we see Jane looking for a group of zombie to get fucked and that would lead to a Game Over.
So that when we lose a fight, we would have the little silly scene, and we get Jane back to where she is.
When fighting bosses, a defeat = Game Over with a scene showing Jane getting fucked by the boss.
Otherwise, other than that, a shame not to have a final scene of the girl and the zombie by going down the aisle. For example, see her on her knees in front of the zombie to give a kiss to the penis of the zombie with a smile like a mark of submission.
Beside that, I note that the fights are well balanced and original, it reminds me Survivor Sarah. Small bug between successive fight concerning the lewd attack.
