I think what is important about this tech demo are the animations because most VN are mainly 2D without animations.
Im not sure if whoever made the engine is going to read this but i think it has potential for something but is waaay far to be polished, not only the engine but some of the characters too, they do not look bad but i feel it could be better
* Animations overall are great, but idle animations have a feeling of a uncomfortable pose since they do an animation and then go back to that idle pose, it would be more nicer if they have multiple idle poses to not have situations where the someone rest his arms in his hips to a second later let it loose again
* The facial animations are good, but the characters don't react to what is said to them until it is their turn to speak, they just stand still staring at the talking partner without an expression
* The hands are fine until you look at them...They do not move their fingers at all
* Sometimes when a person fades away, you can see them naked.
