Anyone familiar with this game?

I have been playing in since yesterday and find it interesting, it's a fun little shooter, with a cutie waif protagonist, destructible clothing, weapon customising and a curious ability system.

Unfotunately it was made for the psp and it's controls GREATLY suffer as a result. It's also obnoxiously hard in places and for stupid reasons, like how lock on and dodging work, every boss and miniboss has instant death attacks and enemies barely if at all telegraph their attacks.

Also why does it have Parasite Eve characters in it? The don't behave anything like they did in previous games and the setting is entirely removed it's really odd given they didn't have the title for selling on the brand.
