I'm going to try to be as civil as possible DESIPTE it not really being in my nature, perhaps you didn't know.
This game is pretty straight forward, the walkthrough only really tells you what choices give you certain points or how to get specific sex scenes. I'll give you my take on what's important, as sex scenes are pretty much achieved by simping for that character, you'll get it eventually.
-Corruption
-Power
-Skill
-Public&Government Opinion
-Affection (in one noticeable case as of v0.951)
1. Corruption
This determines the 2 ways you can play this game. You can either have a low Corruption value which would be the Hero Route, or a high Corruption value being the Evil Route. Either way doesn't really change the path of the game, but it DOES effect certain paths (killing off a character) or changing dialogue based on actions. Some Corruption related choices are hidden based on the value, i.e if it isn't high enough. Raise this stat by being bad or giving into monster related options.
2. Power
This is used during fights, unlike Corruption you ALWAYS want to strive for this being on the high side, if not; at least make sure your Skill stat is high enough to compensate. The points work like a check, if your power isn't high enough you may not fight as efficiently and miss a few things or it will flat out lead to a Dead End (death to last save). Raise this stat by training whenever presented or picking the right options during a fight.
3. Skill
Used much like Power, this will appear on the lower side; top Power lvl would be in the 60-80s while skill will be 8-13 (as of v0.951 without end update spoilers). As mentioned before this is a Power alternative and in some cases may be required despite power, increase this much like power as much as possible. Raise this stat by training whenever presented or picking the right options during a fight.
4. Government&Public Opinion
These stats only really change the dialogue and general vibe of the game. If everyone hates you it'll feel like it, if they love you then all the better. Raise or lower this stat by using your brain.
5. Affection
Probably the least important stat, if you follow a path for a character or characters this stat will practically raise itself. Just pick options that feel right in dialogue as you do in literally every game. There is currently only ONE case in the game where choices you've made have actually LOWERED a certain characters Affection thus making you miss a scene (hint: police don't like evil cop killers). Raise this stat by being a simp.
Tips:
1. Check your stat window often. If a choice feels like it's important see if anything affiliated with that character you're talking to has changed. You don't have to do this for EVERY choice though, as most are just there to shape your character or get misc. information.
2. SAVE AT THE MICHAEL SCHOOL SELF DEFENSE CLASS. This is arguably THE most IMPORTANT choice in the entire game, and allows you to either save a certain character or get an outstanding amount of lore. It also can determine if you can go full Corruption or not.
3. SAVE AT THE SHOPKEEPER ITEM CHOICE. It is yet another IMPORTANT choice, and can determine many factors after it. This will help more so on the lore choice mentioned previously rather than saving the character.
4. SAVE AT THE "LEFT" OR "RIGHT" CHOICE towards the beginning of this update (v0.951). This determines lore or character saving, and arguably many other factors that will come in later after this update.
That's all, if you have any questions they should probably be specific, as no one is going to hold your hand by making an overly complex walkthrough of every little detail, too many hidden choices. I know how to get every sex scene too so if you need a specific number lemme know, I'd be more than happy to help in either regard.
Lore wise your best bet is probably
ZeronZanara he's pretty much hacked into the W.W mainframe and has access to Patreon.
Path wise expert is probably
DrakoGhoul, he's a cunt, but he gets the job done.
I'm a bit of a jack of all trades, my memory comes and goes. Though I am an expert on sex scenes I guess.
