hey,
the money comes down randomly
so just play and you will see it drops. its a game with kind of luck and skill
. because of that you just have to pay if you got a nice highscore and want to enter to the ranking .. if not you can play until you get the score you want. you just loose life if they fall down completly
you can hold the matrix also up with your player down and get points for it
. Also the special items are luck to get
