Alright, got my game patched and played it with a more concrete understanding of the mechanics. These are my observations:
-Marisa, formerly my favorite character before I knew how scoring worked, seems pretty bad now. Once you shed your items she just doesn't have the strength to shotgun many enemies, and she now sucks as killing midbosses unless you can manage to chip them down almost all the way before you stun them.
-Nitori seems amazing now (up from just great) since building armor out of items now basically doesn't matter and she can recollect her items almost instantly if you park mid-screen, letting her mow down waves upon waves of random enemies with huge score multipliers.
-The Hisoutensoku stage seems like the hardest one in the game to me by a long shot. It also might be the most fun.
-The appliance items in the Outside World stage remind me: Keine isn't in this game at all, is she? I was hoping she would pop up as a playable character or at least a boss like in the first one, but I don't think I saw her anywhere. Patch in Keine, TasoFro!
-In fact, now that I think about it this game has a very tight focus on the last arc, doesn't it? It's almost strictly UFO onward. No EoSD characters at all (except Sakuya, but she has an in since she was playable in several games in this arc) is especially surprising since fangames are usually swamped with them. There is a PCB stage though.
-Is the character who teams up with Yorihime for the Forbidden Arcum~Hour Elixir-type attack at the end supposed to be
Spoiler:
Chang'e[/url]?
The mechanic for money acquisition is really weird. Even if I did perfectly on normal, my total money is always minus a million YEN. On hard though...
So I decided to translate it with google.
But even if I translate it, I still don't know how it works.
My best guess:
-Selling Time-Some kind of clearing time bonus. Alternately could have to do with the leftover items after each stage.
-Expenses-Maybe something to do with purchasing items in the store? Did you buy a ridiculous number of items to get a penalty that big?
-Compensation-Maybe something to do with characters? Maybe swapping characters a lot incurs a penalty, or maybe better characters "cost more" and give a bigger Compensation penalty?
-Medical Expenses-Penalty for taking damage. Maybe based on continues and/or lives lost and/or hits taken?
-Something With Kappa-The generic kappa on the stage select screen have a lot of dialogue, so my best guess is that they're telling you about special scenarios for the stages and this is the penalty for not doing the scenarios?
Still a lot of questions left unanswered. How does scoring work? What are the kappa saying, if anything? What's the story of this game? Hopefully someone fully translates it at some point. A user manual translation would be great.
