Making this to pass on some hints that may help and to pick up some hints that may help me.
My biggest hint is...
Use the ghost crypts at the front and upgrade them to the fear class tower. This helps amazingly against cloaked guys and those pesky sword dudes. Multiple Crypts is essential to get the best medal for a level.
You want them at the front because the crypts will hit first and all the shots will hit the cloaked guys and will have a large chance of fearing the sword guys.
Remember your towers get exp if they fire... not if they hit. So 5 crypts that fire 5 shots at the first dude will ALL get exp.
For the final level I finished it at level 35 brilliant without much problems.
Oh yes I got the area kill temples on top with crypts fear support down the road. The ninja boss take only one hit from temple but remaining life is easily blown off with max magic.
The temple has the highest one hit damage and able to kill hidden ninjas if there is something else within range that cause it to scorch anyway.
My biggest hint for getting brilliant is simply to meteor, meteor, meteor.
Max out cutting trees for gold and cost, meteor damage/mana cost,and max mana and regeneration.
The dens are the best tower, because fully upgraded, they have the best damage output, the continuous damage from temples, and the best DPS and accuracy.
I find it's still best to go with similar amounts of each tower, because there are areas in each map where certain towers excel, and you can only place a so called tower on a type of ground.
I find crypts + dens go better on high platforms then dens, but it's a personal preference.
