Also, searching for rpg in iTunes will also bring up the game.
It's like any rpg from the days long ago, so it's turn based, not real time.
In battle, only fought once. You have a menu on the top, I tapped sword, then you tap the enemy which to attack. The game goes full widescreen for battle, and you characters seem to be newer artwork that looks nicer than what I saw on youtube.
To move, you tap on the screen to make the character move there. Though, if a wall is between you, you may have to manually guide the character around it. You can move really fast by double tapping to cause the character to run left, right, and up and down, until hitting something or you tap again.
The menu has the plain iPhone interface, so it's a little jarring from the style of the game. At least saving is quick. Just tap an empty of filled spot and it's done instantly, no wait. Though, I hope it doesn't get too complicated when I get more items and characters to constantly go through page after page of the iphone interface to equip things.
If you want an RPG, I think we lucked out to get something like this and only $5. Seeing how this was a real console RPG, it should have quality and a classic feel to it. And comments on youtube mentioned it was similar to Lunar, and overall a good game.
EDIT: Also, I just noticed in the settings for iPhone you can find extra options for Vay.
Like, turning BGM, SFX off and on, or all sounds. Switch battle sprites to original graphics. You can rename any of the characters. Also a hard mode.
