Choose your cards carefully and play them strategically - there will be heavy resistance along the way. Battle everything from small mutated fungi to powerful giant goblins and nagas!

In addition to the story-driven single-player campaign in Prime World: Defenders, each players’ experience is unique thanks to custom generated missions!

Be warned!

I have enjoyed the game for weeks. I made several purchases of stars and coins during a sale promotion.

Today, I clicked to purchase a set of cards for $9.99. I had a $7.50 credit on my iTunes account and thought I would use it up. During the purchase, I got the pop up that iTunes terms had changed, I clicked through and accepted the updated terms to continue my purchase. Afterwards, iTunes asked me again if I wanted to purchase the set for $9.99, I clicked yes. Purchase successful..funds no longer in iTunes summary. However, it did not redirect me back to the game. So, I opened the game. No cards. I closed game and rebooted, no cards. I emailed support, no response. Two hours later I get the support email returned.(mailer daemon auto response) Email denied, returned to sender.

How am I suppose to get my purchased card set or money back if I can't email support? Is this game no longer supported? It should be removed from iTunes Store. My feelings are this game stole my money and I have no recourse to even notify them that I am missing my purchase.

I will change my rating to five star if I could get some kind of response from here, email or the Facebook page.

Contacted email for refund.

Great but can be improved still

Great tower defense game! Seems like it's completely free to play so far. Every once in a while after losing a level on hard the game crashes. Also this heats up my iPad pretty quick. Maybe a lower graphics setting option?

Simply fantastic!!!

Just when I thought all hope was lost of finding a decent game this one changed everything I've never played a game like this before so yeah this game is perfect thanks developers.
