Extra CGs?

#include <disclaimer.h>

I just finished the game and as I looked through the gallery to make sure I had every CG unlocked I noticed something odd.
In page 3 of the gallery has one and page 4 has five CGs that don't seem to appear through the story. I did a fast "skip run" to double check – those CGs were not used in the game!

So... this leaves me wondering... Judging from the contents of those CGs, I get the feeling the game was supposed to be longer and have more story in it, possibly with more choices, but was cut for some reason. Hmmm...
Any thoughts on this people?
#undef speculation

though, at least they added the CGs for us to see, even if not present in the actual gameplay...
And it strikes me odd that I did not find a single thread on this forum already covering this oddity.

Well you have Miyo covered with flour, egg and wet in a kitchen and both Miyo and Narumi holding a sash. To unlock them all you need to do both path. These could be bonus CG or just cutted content. I tried to ask the artist about that never got an answer. You could always ask Sekai Project about that.

The CG of Machiko standing with her back against a tree on the 4th gallery page is also not in the game.

So, does anyone know what these "extra" CGs mean? is it just a bonus? or maby a hint to a sequal?
