Ok, i got this from the early release promo, and have played it with a passion since! And that's coming from someone who doesn't like highscore-one-more-time games unless they have unlockables.
This game.. is just super fun, jumprocketing to land on the heads of the crowd below. You get "diskettes" which give you powerups for the current game, and once you collect enough, they unlock the second and third world.
The replay when you lose is just one touch away, making it very compulsive.. not to mention the bullet-time when you narrowly avoid a rocket.
This game does everything perfect for its kind. The only thing i would like to see is ..yeap, unlockable content, constumes, characters etc.

5 stars!
PS on my third try i did a score of 60, haven't been able to come close to it since but i keep trying!
