Hey there! Yep, I did the technical part and it really suffered due to us having 2 artists, one 3d modeller and way, way less than one programmer due to me also writing the story, doing sound design, animations (including the h-scenes), UI layouts, gamedesign, etc., etc.
But we know of this gap and I'm already working on patching it! In fact, a lot of the most atrocious stuff is already fixed, but we're waiting for the jam to end to avoid getting an unfair advantage by posting a more polished version.
