From a purely visual novel standpoint, the game is entertaining and well-written, but it fails to make use of the one thing that makes it unique. It has the love it needs, but it will need more training before it can truly be called a "good boy."
Rainswept is a heavy game. Its sad piano music and endless poetic rainfall underscoring the human tragedy depicted. If you're capable of shouldering the game's baggage, Rainswept provides an "entertaining" tale. I certainly "enjoyed" it. However, if what you're looking for is a fun murder mystery to sink your teeth into, you might be better off seeking clues elsewhere.
Yet, while I had issues with Neo Cab, I will admit that it's worth the fare. It perhaps didn't set my world on fire, nor do I think it's going to climb atop anyone's list of favorite games this year, but it's at least a nice ride while it lasts.
Umihara Kawase Fresh! is easily my favorite entry thus far. I hope that the changes to the framework and the added accessibility manage to hook some new fans. Maybe this really is a fresh start for the series.
So I guess what I'm saying is, if you go into Gato Roboto with the only expectation being "Metroid but with a cat protagonist," you won't likely be disappointed. But if you hope for anything beyond that, you'll likely wind up entertained but unsatisfied.
