Fun game, very addictive. Keep them coming!
Ignore the haters. How many games have they made?
Whiners cry about playing a free game... maybe they want a refund? Mommy?? WAAAAAAA
Completed using just basic Mages. The special characters seem to be a huge waste of gold. Throw mages down everywhere you can, pave and throw mages down, then start upgrading them. Pay attention to the next waves weakness to determine which ones you upgrade. Use a bunch of Dexer in the Rat Hole, but nowhere else. Fire and energy mages are the most useful. Fire mages upgrade faster.
