not a very good game in general; gameplay is mediocre at best, and the only 1 life ever concept is an incredibly horrible idea.
what's this doing on the front page?
also 2 days, this seems a lot easier than the first one...
anyways, about $2800 on first day, fuel tank to 6, rockets to 5 each, fuel sucker and radar to 2, everything else to a better launcher. e-rockets help a lot if you can afford them, but not necessary.
