Let's hear it for Kingdom Hearts Lite
Along with a slew of free match-three games, this is my latest obsession - Kingdom Hearts Unchained.
The touch controls work really well and the art style is so friggin' cute. I spotted this little beauty at E3 this year, and I'm using it to hold myself over until Kingdom Hearts 3. I've been able to play this for a couple weeks now without having to spend a penny. It still blows my mind that so much effort can be put into making a game in hopes that people will voluntarily pitch in some dough.
Obviously, this has nowhere near the depth or addictive power of a console Kingdom Hearts game. Think of it as Kingdom Hearts methadone.
