Mastiff, a San Francisco based developer and publisher of videogames, announced today that Nihon Falcom’s action-RPG, Gurumin: A Monstrous Adventure has become the first third-party PSP (PlayStationPortable) system title available for online purchase and download to the PSP system through the PlayStation Store and is available now.

Upon its release last year, Gurumin immediately won over the hearts of countless reviewers.

Gamespy, for example, said “Gurumin: A Monstrous Adventure delivers the classic Japanese RPG experience and is simultaneously adorable and hilarious. If you’re only planning to get a single RPG for your PSP this year, this could well be the one to play.”

The Associated Press said “Gurumin” is filled with a uniquely Japanese sense of whimsy that translates well into English, and it’s one of the nicest surprises of the year so far.” Review site Deeko said “Gurumin is one of those rare games that should be in every PSP owners collection.” Console Gameworld, echoed the sentiment, writing “Gurumin is definitely one of those titles you have to pick up, period.”

“Charming, full of personality, and with a gentle sense of humor, Gurumin is a bright and catchy portable game,” said Heather Campbell of Play magazine. And Geoff Haynes of leading gaming website IGN.com, called Gurumin “… an excellent title that should appeal to action fans.” Gurumin’s strong reviews earned it a place in the top 50 of almost 1100 PSP titles ranked on IGN.com.
