I like the character of the game. I think the interactions between the two girls could be very funny. But the promise of having a jetpack isn't quite delivered on when you just remove gravity. I just feel there are so many cool things you can do with a jetpack. Also the level design feels like it should utilize it. The levels that I saw were suited for a platformer, where you don't have a jetpack. The shooting feels good though, I like that. I think if you find the fun potential in having a jetpack, you'll find the fun in your game.
