Saenai Heroine no Sodatekata.

It's an anime about... making a game... that appears fully congruent with the contents of the anime...

In short, it seems to be a metacircular anime. It's worth watching because of the way it plays with tropes, and the origin of those tropes; it's marginally annoying in that many of the tropes it plays with are of the harem genre. There may be something more going on in the background, but I haven't watched enough to tell. It may be especially interesting to people who have long experience with japanese animation.

The first episode is fully representative, so I'd recommend having a look if the above appeals.
