Time to post some pics. Keep in mind that the current release is exactly the same as the one they released last August on Playism Japan, with a few things translated by ZUN himself.
A comparison of the launch menu, and contents of the Playism game folder:


Comparison between the Japanese (CD version) and English (Playism) config program:

What you get when you click on "Save and Close"? An untranslated message that may appear as gibberish on your system.

The title of the main game window. Somehow ZUN believes calling the game "TH14" instead of "Touhou Kishinjou" will be enough to make it English.

He also did not update his readme file properly.


Left: readme.txt after applying the 1.00b patch to the CD version.
Right: the Playism version still has the 1.00a readme.txt.
We are pretty used to how ZUN half-asses everything, but to most people who are not Touhou fans, this will come as a shock.
