Okay, now this is promising: Lilith has actually made a new game.

It's a normal, vanilla Lilith-Soft title, but at the same time, holy Goddamn shit. Four and a half years, and they finally produce another original VN. At this rate, only another three or four presidential terms until TY3!

(I can't link to it directly, thanks to Google's new bullshit censorship. But then, if you can't solve this puzzle, you don't deserve to see it.)
