Does this have anything to 'ore no imoutou [a lot else I forgot]' or is the title of the game a coincidence?
Just "coincidence". It has nothing at all to do with OreImo.
The past couple of years has seen a rise in overly long titles for manga/anime going mainstream(ish). Some can be decriptive of the series (like this one.) Others, not so much (AnoHana being one such series).
