Here is a review of the game that no one asked for...
I sub to him when I can. But I can't always afford it. So in the in-betweens, I come here.
The Dev of Mud Blood is pretty consistent with updates / patches. Usually it is 1-2 months. There is a record of his updates on his Discord.
The updates are very gradual. Mostly added animations, and minor gameplay additions. He adds new monsters from time to time. But usually nothing too big. He usually adds a new feature every few months, but it usually is something that is quickly outlived within 5-10 mins of gameplay. Not criticizing, just explaining.
He has mentioned a few times that him and the other developers want to create an open world game where you can do anything you wish. They use another game as a reference / example of what they are working towards, but I can't remember its name. He basically states that Mud Blood prologues is really just an "Asset Builder" / Playground for the devs on the way to building their "real" game. So you will find a lot of placeholders and implementations that haven't been fully flushed out yet with plans on implementing them in the future.
IMO The game is decent in its current state. If you have never played it before, it has a decent play loop of a few hours. And because of the nature of the content, you may find your self playing that loop more than once from the beginning. Unfortunately, there are a few ways to cheese the game due to built in mechanics, and once you get the hang of it, you can beat the game very quickly (usually 20-30 mins) in its current state. It doesn't take long to discover the few hidden mechanics that make it easy to beat fast.
Overall the game is really fun. It has some interesting mechanics, and some re-playability. However, in its current state it is very short lived, easy to beat once you know the mechanics. But it has a LOT of potential if the devs would ever focus on adding mechanics like learnable skills or base building which seems like one of the mechanics that are in the far off future. I really wish they would focus on the base upgrading and leveling aspects and/or adding other things you could do with the girls in the form of BDSM, but it seems this will almost never come to fruition. I have followed this game for a few years now, and it is heart breaking to know great the game could be, but to see very slow minimal development over the years.
