bad update

Thanks for the updates!
Thanks for reading and responding to our reviews!
Despite being such an old app(i think i was playing this on the original iphone when it first came out) and only having 144 users currently (according to leader board)

I gave this a 2 star on 2.0 now upgraded to a 4 star now.
There are still things i wanted though

In the order of importance:

1. Retina Display Support (Seriously the Graphic suddenly look really bad after the update on a retina display)
2. In version 1.0 or whatever it is before 2.0, there was a counter showing how many shots i have left, would like to have that back
3. Multitasking support(instead of auto-saving in game)
