Boxed In...
A cube, if you will. Or, loosely based on, or at least is somewhat influenced by the 'Cube' - which is a great horror movie.
And I tell you what, the basic premise works fabulously well with this VN's incestuous nature - do it, or die...!
If you are a fan of incest, then you'll definitely want to check this out. It is far from perfect, though.
The pacing is pretty quick - which is okay. But, the game would be better if things were slowed down, building up the 'tension' before release - if you know what I mean

.
I did think the premise - to force incest, in this case - was watered down and had a lesser impact as it seemed many of the characters
were totally up for it, or had already fantasized about it. OR, already doing it! Bit of a shame, if you ask me.
The H-scene animations were mediocre, but overall, I did think the dev has a bit of an eye for making H-scenes in general. Just slow the pacing down a bit. There be fap material here.
Sound is grossly mis-used here - that is, no music, not even background noise. Just the occasional SFX for a door opening, for example.
'Tis good for an incest game, but could be better, much better. And it is an average VN overall.
This Box[ed In] is one you may like to jump in and out of, just for the fun of it. Because, you can.
