Translation (thanks to Fusion):
There was no February.
Now then, once again snow has suddenly fallen and it's gotten cold this year, but it's finally starting to feel like spring a little.
So, I'll be participating in the Hakurei Shrine Yearly Festival (Reitaisai) again this year.
This year's product will be
"Touhou Project #13: Touhou Shinreibyou [Mausoleum of Divine spirits] ~Ten Desires." (trial version)
Touhou has finally made it to number 13 (not that there's been much fuss about it being #13). When I think how long I've been releasing one work a year, there sure have been a lot of different game systems, haven't there?
I've added a few things that will make the game system a bit more complicated in order to keep the difficulty level down a bit.
Basically, the story is "Suddenly a large number of spirits appear - the type that are called divine spirits! A young girl appears to investigate, knowing this can't be left unchecked."
The main characters include Reimu and Marisa as usual, as well as Sanae, who's trying to learn to use divine spirits effectively, and Youmu, who's here to deal with any divine spirits that aren't under her control.
One of my goals is to make it fun to just beat all the enemies even on lower difficulty levels, so I'm releasing a trial version to see how it went.
Watch out for our advanced "business as usual"!

I SEE SPELL PRACTICE AND CHARGED SHOT... WUUUUT
To those new to this: This is Touhou; some crazy-@$$ famous shooter (classified as Bullet Hell because of the several bullets you have to dodge) in Japan that's made its way around the world; famous for its ladies and its music. You thought Pokemon conventions were big, you haven't been to Touhou conventions in Japan. This one is its 13th series now... well, 13th of the shooter series; as there are several spin-offs from it such as fighting games and ala-Pokemon-Snap-style even.
