@NormaTheNorman. Ummm... the summon troops levels don't mean they need to all be summoned at the same time... ya know when one dies, you can summon another and hence achieve the achievement.
can you make it so that it can run in the background? i am disappointed when games always pause if i click away for a min. I recently saw a game that actually had this in the options screen.
too bad the game is soo buggy. I gave it a solid go to give it an honest opinion, and there were too many "ghost" plane crashes. Please fix this as i really want to give this game another go.
Thanks very much for saying so!! I highly appreciate it!
