First of all, great feature with the implemented AG save system, so you don't lose any data (though the NG password would be even better IMO). The game really reminds of Kingdom Rush in the way that it uses the same type of save interface, is a Tower Defense game, and works pretty much the same way in control and interface. Contentwise, however, it's completely different. The enemies, the maps, the towers, the graphics, the music... is all different. I loved Kingdom Rush, so any game like that is a guaranteed hit. This will be loads of fun! One thing that would improve the gameplay experience greatly is medals integrated with the NG API, it would be much more rewarding with some of those. Keep up the great work!
