I'm gonna add a couple of tips for everyone that's trying to pass the game
Full map made by the developer:

...
- You will need to at least have 4 radiance bombs...
- Farm the attack sites where you just have to smash the S letter on your keyboard...
- If you want to raise your depravity/corruption levels fast, go over to Mayu, even if you have no aphrodisiacs or lust, she will give you good chunks of Sexual Experience (what you need to level up Shion's Depravity)...
- If you want to go full futa route, on third floor you have the first option for this, but you need to be at least level 5 of Depravity...
- At level 5 of Depravity you unlock the "Lewd Battle" type of battles, Hinako explains it properly so I'll skip doing this, but what I'll tell you is that the breast poison is very, very good and you should consider it in case you want to win against any of the bosses this way.
- "Lewd Battles" are only available against heroines and the final boss...
- Always, always, ALWAYS, whenever you find a teleportation site, go through it, not only because you will need it, so the game records it as a checkpoint site, but also because if you don't use it you might get lost later on and forget about it...
- Give up on passing the game on 0 Depravity or Depravity lvl 1, it's basically impossible and the game's not meant for you to pass it like that (and you'll miss some of the spicy stuff)...
- Once you have futa status, return as quick as you can home, you will lose it, but, if you go to Saori, she'll give you the possibility to turn into futanari with one of the items from her sex shop...
(I'll update with more tips if I find more helpful stuff)...
