Guys is this game worth the download??
Hard to tell since it will depend on what you like. Most people here will of course say "yes" (otherwise we wouldn't be watching this thread for updates). It is a sandbox, which many people dislike but I personally like, it is hard to try and get as much content as you can, even with Wiki support, it is a game in development so if there's a new version some progress you made may become undone, it does not have any overarching storyline. If any of that bothers you, it may not. It however has a shipload of content, many girls with pretty different characters and individual arcs, some as of now more extensive than others, quite a lot of humor and generally decent writing, graphics are a big plus for me too (but you can see whether you like it in the preview pic).
Is there some worth noting NTR? How good is it?
If you are looking specifically for NTR, this may not be your game. One character can have "proper" NTR scenes, another gives a blowjob before you're a couple, that's it. As for "how good it is" I cannot say, since personally I despise NTR so I have no idea what specifically makes people like it.
The wiki is helpful yes but a linear walkthrough on a PDF would be more helpful to both the creator and the player I think.
As has been said, a "linear walkthrough" is almost impossible. Since this is a sandbox, doing stuff in different orders will result in different outcomes, and the number of possible paths and outcomes is immense even if we ignore stuff that doesn't change the storylines.
The other aspect is that there is randomization in the events. So even if we agreed on a path (say: we want to collar all girls and make them pregnant) and give a step by step guide, step 87 "meet Samantha at the pub" may fail since the RNG decided she wouldn't be there that day. And now? Of course you can try to continue going to the pub until you finally meet her and then try to continue - but by then you lost time that Sasha used to get back with her ex and the investigation at the office finished finding you guilty because you missed steps 102 through 113 to prevent it. So maybe better to play 102 through 113, but then something else will depend on having met Sam at the cafe. So suddenly we need footnotes and another set of branching paths until they merge again depending on whether you hit or missed that 50% chance (which also may be lower than that). Also you need to be extremely thorough, if you miss one phone call giving you a kink point in a list of ten calls the guide lists at that point, you may miss a threshold later on. And you cannot shortcut - "I don't like character X, so I'll just skip her story" unless you do some research in the document.
A wiki with general information about how things work really is the more comprehensive way, especially since it also allows you to enter at any time during the game to get the information I miss. Which in this game admittedly more often than not will be the information "you fucked up buddy, best to start anew".
Finally I would argue that an absolute step by step guide, even if it worked, would not be much fun. I experienced it at "Time Loop Hunter" - which I love, so this is not meant negatively - which has a
very convoluted story approach. But nothing random, so dev makes a step by step guide to see all content in (probably, with a game like this it may be not too easy to really know) the minimum amount of steps.
Problem (a) with this is: it does not help you to continue if you got stuck at a certain point in free gameplay. You would need to find where your problem gets solved, check all previous steps for whether you did that, which is immensely complicated. Problem (b) of course is: if I do not want to make any decisions at all and just repeat the precise clicks from a PDF - I might be better off with a kinetic novel. Which offers the same "just reading a story" without any Alt-tabbing between windows, double checking I didn't miss anything, rollbacks after misclicks, and so forth.
