Unfortunately, I believe Houkago Play misses the mark in terms of both story and entertainment, making it mediocre even to moe fans like myself.
The first problem is the story. As you can assume from the fact that it's a short 4koma series, it doesn't have much of a plot. However, the couple in question is far too unrealistic to tingle the hearts of any but the most delusional fans. I don't think the mangaka meant for their relationship to be taken seriously, but it's obvious that it's a totally implausible situation. It might generate that "warm and fuzzy" feeling in you if you're into purely fluffy romance, but don't expect your suspension of disbelief to last. It's also worth mentioning that the art is below par, which ruins the heroine's potential moe appeal.
However, having said that, the real problem with the series is the comedy. Quite simply, it isn't funny. Unlike most meta/reference comedies that focus on subtle references and quick punchlines, Houkago Play feels more like listening to a couple of gamers talk. Many of the comics don't have a punchline at all, which feels extremely awkward in the 4koma format. There are a handful of funny moments, and the dialogue is always entertaining, but "entertaining" doesn't cut it when the story is nonexistent and the character interaction is blatant and ineffective fantasy fulfillment.
The bottom line is that I do not dislike Houkago Play because of its genre or target audience - in fact, I'm a proud member of the target audience. I simply dislike it because it could have been so much more with less time spent on the "romance", or, better yet, jokes that are actually funny.
