Today's Free App of the Day is Terraria
Originally $4.99

I just picked this up for $0.99 on iTunes (think it's still on sale) but haven't had time to play it, picking it up now for free on the Fire. Well reviewed! Some of the one star reviews say they couldn't get past the create character screen using non-Fire devices. I didn't have any problems with my HDX.
