I really don't use this term lightly but this one is a real gem. Pixel Kingdom Google Play Store Description "Command your army to victory! Pixel Kingdom is an RPG Defense game in which you collect Units to fight for you across infinite levels. There are tons of Units, Items, and Gear to unlock with your hard earned Gold. Pixel Kingdom features multiple environments with 50+ unique enemy units including rare and powerful Dragons. Complete with a full set of achievements, Pixel Kingdom is an easy defense game to pick up but hard to master!" As far as I know it started as a kickstarter project and it's for free. You should give it a try.
This really is a fantastic game. I give it 4 stars, but the developer is constantly updating it, and is very responsive on Facebook. A model of customer service and feedback. Unlike a lot of games, I feel I really have a voice in it's continuing development. Oh, and the game is just FUN!
