So, I played version 0.21b a few weeks ago, and I was finally able to bring myself to write a review. I remember playing this two or three years ago, and when I downloaded it, I was already anticipating an abundance of content, an interesting combat system, or at least a plot or a vore with fat porn. Now, remembering what I did in the game, the existing mechanics, flaws and bugs, I feel that there are definitely alternatives.
About everything in order. The plot hasn't changed much. It seems that the intro should somehow set the seriousness and intrigue of the adventure, but after that nothing changed. The most interesting (and probably the only important) thing is how Buddy suddenly gets impudent and takes control of Zeno, and is a suspicious merchant. I didn't learn much about Zeno himself, as a creature very similar to the opponents from the first act, or about the world. As a result, why did our main character go on this journey at all (although he doesn't look like someone who is ready for this, considering the number of times when enemies can fuck Zeno), why is he taking risks and why were we asked what we would do after the adventure. I dont even know what's the mood of this game, other than porn. Maybe the plot is not particularly important here, but I have a feeling that something interesting is coming, but it breaks through the doubts.
The action game seemed strange to me before, and it still does now. I didn't upgrade my active skills because they cost SP, so my entire combat consisted of attack, block, and buff. And my main complaint/question here is the useless optionality. I didn't notice the difference between fighting through attack with enhanced attack and through defense and enhanced attack.
And finally, my main disappointment is weight gain, which is why I downloaded this game again. Imagine me when I found out that the only way to get fat is worth twenty gold, despite the fact that you earn 10-15 in about 30-60 seconds of combat. Despite the fact that you have to walk from the tavern to the forest just to gain 1-2 kilograms, although I gained about 10-15 kilograms, I never reached a new stage. As a result, the only WG content I received was a rather dry dream scene, well, at least the shapes were drawn well. After I stopped playing, it dawned on me that I could speed up animations, which would allow me to fight faster, but it probably wouldn't make much difference.
Add to this limited running, long distances (which, although they give a sense of scale, soon get boring and often don't make sense when it comes to WIP locations, such as Kobold camp), sometimes blackening letters in the text and bugs, and you have a very mediocre and crude game with extremely boring farming and gameplay. In the beginning, due to the small length and simplicity of the battles, it seems that in the future they will become more interesting, like the whole game as a whole. I hope this really happens. For now, I don't see any point in playing version 0.22, as in, most likely, several other versions.
Now for bugs and quest questions I found.
1. There are some text bugs. I dont know if its fixed, or I am only one with such problem. I have only one, but I remember that there were more of them.
2. Is this potion supposed to be picked up? If yes, I cant. 
3. I tried to over feed Zeno, and got a bug where it didnt goes lower 24. After reopening the game it has been solved and never happened again, but still.
4. The purple save crystal in the forest cave that people mentioned.
5. I tried to upgrade a skill (I dont remember the name), but nothing happened.
6. After I tried fight Tiamat again (by repeating the battle) and loose (on purpose) I have this and no, I didnt have Dog (thats his name, right?) with me then.
7. Transformation doesnt work for some reason.
8. Where I can find rock for a statue? I found a statue with gem (or smt), but coundnt do anything with it.
9. Dangora box dont regain... something, maybe SP, or something else, I dont remember.
10. Long and short sleep reduce fulness equally.
