Love the humor in the cut scenes and the RPG development of each of your units makes you much more interested in them than just placing random structures and applying 'upgrades'. Have been having fun playing this with my daughters as they are enjoying the story and watching the battles and I appreciate how even if you fail a level you can still gain some experience and currency for the attempt which makes even losses seem worth their time and helps get stronger to go back and win that level. Having multiple difficulties for each level is also appreciated.
