Simply put it is nice to get a totally original game for the PS Vita. Gravity Rush felt to me like a platforming action game. You play as Kat and as the name would indicate can control gravity via a cat (Dusty).
There are 21 total chapters so it makes for a decent length game and provides some replayability for completionists. For me it was a good rent, but I didn't have a desire to play it again.
The biggest issue for me was the controls. You are kind of a super hero type, but the less than tight controls make you feel very ordinary. You end up relying a special moves which don't require much aiming to overcome basic control issues.
However, all that being said I enjoyed the game. The story was good and has a Japanese style. The artwork is very cool and many sequences play out as comic books.
1) good story
2) original game
3) neat art style and comic like feeling
1) controls just weren't tight enough
