I know this game is not released world wide yet... It just came out in Korea for PSP. And it's called Mutajuice. More of an interactive animation than an actual game.
I can't say Mutajuice is an excellent game/animation. It has list of things that I think is problematic.
But, that aside, I still enjoyed playing it a lot. And the production quality is surprisingly high.
There is an a lot of similarities to Gainax/Production I.G's FLCL. Well, the story is that a boy "accidently" drinks juice with an alien origin. And after that, he transforms into a giant robot when he is in "physical" contact with opposite sex. Since this is a "Teen (15 and above)" product in korea, it has those typical anime/teen humors. You know... tripping and landing on female bosom, the female alien character is not aware of different sex, so she shows up in the boys shower etc... I personally didn't find any of these kind of humor funny. Not only is it done like millions of times... I hate it when anything has a non-kid label and it automatically becomes sex and violence related product.
But, I digress... None the less, I did enjoy most of it. And the fact that it is one of the rare original games for PSP makes it worth checking out.
I've been a huge fan of katamary Damacy also. So, in a weird sort of way... this fancomic came about... And of course... my little tribute to Mr. Miyazaki at the end...
BTW... Here is a link to a promotional movie for Mutajuice... [link]
