That is correct. This is our early build, using VNMaker from Steam. We've been focusing on less strenuous projects, to drum up interest and support for the series as a whole, but we're still working on this here, and there.
We still have no clue if the problem that makes it glitchy, is some of the stuff we did in VNMaker, or if it's just VNMaker's dysfunction in general, but we're hoping to learn Ren'Py, and fix the glitchiness.
