It seems the "Rework" of the vore system is, well...
Enemies escape roughly 70 times out of 10 (that's only after the attempt has failed for the 12th time in a row) and seem to be able to hold the player indefinitely.
But the imbalance is incredible, when they eat you and you have 50% or more it is most likely that it will be a game over because it is almost impossible for you to escape and then devour them again and if you are the player and you leave your enemy at 5% it is almost impossible to devour it and digest it
