Some things can change depending of how hard or unstable is for the code.

The New Feliciamaru 4.0 changelog is here
[New Feature] Victim now can escape from the rape by pressing x and y repeatedly
(a) The victim must reach 200 points to escape from the rape
(ab) If the Futa cums, the points reset
(b) Every time you press x or y, the victim gains 10 points 
(c) Every time the Futa penetrates the Victim, escape points decreases by 20 points
(d) When the Victim reaches 100 points, the Futa will trigger speed 2 or 3 and will not go back to speed 1
(e) When the Victim reaches 150 points, the Futa will trigger speed 3 and will not go back to speed 1 or 2
(f) When escape points goes from 150 to 100, the Futa calms down and goes back to Speed 2 or 3 (If escape points goes under 100, the Futa will go back to normal)
[So, the closer you get to escape from the rape, the faster the Futa will rape you, she will not let you escape that easy]
[Also, due to the AI tend to be very slow pressing buttons, the changes down here are for the AI only]
(b) Every time the AI press x or y, she gains 50 points or (b) Each 2 seconds, the AI gains 20 points [I still need to test this]
[New Feature] The Futa will be able to trigger second stages (same position,but less clothes)

[Changes from Feliciamaru 3.0 to 4.0]
[New] Now you donīt need to hold the button anymore, you can press Speed 1, 2 or 3, and the Futa will repeat the animation until you press a button again
-Release Victim chance for the AI reduced from 50% to 25% (Because now you can escape by yourself)
