Money earning guide! The reason it seems so hard to get money is each replay earns LESS money (diminishing returns). They key is to replay the best levels until it only gives you a few thousand for a replay. The hidden levels are the best ones to replay, some of them give you $40,000 on the first try. Doing this strategy I maxed out my upgrades and got 6 stars on all maps.
The tutorial guy says click anything on the screen and he'll tell you about it, but he doesnt' tell you about the tips part at the top or the part with the funky purple symbol and $2 at the top when you click them. I have no idea what the purple symbol means.
Thanks for updating this game on feb 15th and making it incompatable with flash 8 (blank screen, game doesn't load). Now I can no longer play it in my current setup.
PaladinJosh: I didn't ask for removal. I think its a great idea... IF it only shows waves you've survived!
So if it were patched to only show waves you've lived through, it would be ideal. Then you don't have to remember what they were.
But to know in advance the exact composition of the enemy assaulting you is a bit unrealistic, and makes it too easy and boring.
Wave browser should only show waves you've survived so far! (i.e. if you died at wave 10, shouldn't show the other wave stats) Makes the game too boring to know how to build in advance!
