Okay, I got another question now. I used the healing you told me about and grinded a bit, then beat the witch, then the game just ended. So I was like "what the fuck?" Where's all the h scenes? I went back to town and looked around, but couldn't find any. I checked the recollection room and saw a ton of empty spaces, so I know there's a bunch of scenes, but i'm just really REALLY shit at playing this game, i guess?
Can I get some more help?
The game is just really unconventional in how to progress the H-Events. (Dare I say, while I enjoy it in terms of the content it has, it kinda sucks from an actual game design perspective).
The tldr is: You can challenge the Witch at any point. Losing to her will result in one of 4 bad ends, depending on how far your corruption has progressed at this point while defeating her will lead to the good end, regardless of where you are in the actual corruption part of the game (which can also lead to a lot of confusion if you hadn't yet "found out" about what exactly is going on.
The exact way of how to progress your corruption changes over the course of the game, but in the beginning it is triggered by letting your lust build up till you need to relieve yourself.
Your lust increases by changing between maps so the easiest way is to simply move back and forth between the city and the academy a bunch of times until you trigger a cutscene.
You'll then repeat this until the game actually points you into a direction.
