(flash) Gem TD - Beating Extreme

The tower turnout wasn't as good as I would have liked - more perfect topazes then I could have put to use, so I leaked once, but that's okay.

HOW TO BEAT EXTREME
Start with silver, upgrade it after wave 2.
The creeps have to go to each checkpoint in order, so construct a maze (like I have) that forces them to go in and out past the maze's center at least twice. This allows you to beat ground foes with even subpar tower placement, so just make sure that you have enough anti-air ability.
When choosing towers, choose the best tower that you haven't gotten yet; this will make special recipe construction easier later on. Just make sure, again, that you have enough power to kill fliers.
Finally, once you've built enough of your maze, keep replacing stones in the middle and spam perfects, greats and special recipe towers around a middle aura gem(s).
(Endnote: If you get a perfect opal, do NOT upgrade it unless you have a second; perfect opals are better than black opals, at least for now.)
