Forgot this game had a functional walkthrough. Whoops! So, I made one in pdf format along the same lines as the one I did for Dark Whispers (I'm just planning on doing the whole series at this point).
Since the game is so short, and I feel like the exploring is part of the fun, this guide provides an "Explorer's Guide" designed to help lead you through without actually telling you exactly what to do (basically, what order to visit the rooms, but only hints as to what's there). It also has a concise list of the H-Scenes and how to get them, and a more standard step-by-step Walkthrough of how to get all the scenes and finish the game (including roughly where to click on things). It also discusses how to spot the potential "black-screen" instant deaths by observing the themes they relate to. That part is, admittedly, a bit self-indulgent, but once I noticed what the items were that cause the sudden deaths, I found it really interesting.
I also went through the entire script to fix some of the translation issues, add a couple of unused images I found, and generally give it a good polish.
I'm waiting on Nikraria to review some of the minor changes I made before I put up a patch for that, though.
There hasn't been any complaint from Nikraria, so I'm gonna go ahead and give you the patch.
Edit: I couldn't get the "crystal/cristal not defined" error to repeat for me, but I had some idea what might have caused it.
So... I think I fixed it, but someone will have to let me know.
