Great tower defense and strategy – Four Days: World Defense Review

I've played many tower games and this one scratched all the right itches and opened a few new doors. Coordinating anti-air with effective ground and enemy routing is challenging and fun. Great stuff and thrilled to have so much for free. Love the fact that this still runs great on my older itouch device. Still playing it .. No idea how many total hours have gone into this ... Wish list: ability to turn down graphics power to cut down on battery use. Sometimes buttons are unresponsive or slow on my 3GS. Have to hold my finger or press twice.
