Ryujinroku?

First of all, I'm sorry if this is the wrong place post this, I really don't know. 
I've seen a couple of videos of what seems to be a game engine made in Visual Studio, Ryujinroku.

The videos:

Comments anyone?

That is actually a gigantic tutorial teaching you how to program an STG in the C programming language.

EDIT -- My bad, I think it's a combination of C and C++. Increment the URL number to go forward in the tutorial. It does come with all those framework files, though, so I guess it's sort of an engine.

Here, download. This is the 1.02 version, and it misses some things from the video (I believe those were edited in later on... or they were cut as those are belong to ZUN), also you control Sanae. It's actually quite hard on the computer, at least on mine.

And it freezes when Aya appears.
