This game was pretty subpar for its time, and feels even worse now. The success of any given run is completely out of your control. No platforms to send you higher? Enjoy your $0.00 and wasted time.
Oops. Bought the first Oxygen Bar Angel Upgrade too early, now I'm down a few hundred million angels and gaining them back at a remarkably slow pace. There goes my attempt at moon progress...
This game is almost 7 years old. It's from a different era of flash gaming. The dude who published this game's profile is this: "3 words: random, hard and sandbox." Granted all this, a less unfair version would be totally fun, but I don't suspect it will happen.
