Absolutely luscious presentation. The lively animations, the tasteful sound effects, the catchy music... even the menus and UI elements are bursting with character and flavor.
The world also seems engaging and mysterious, although I wasn't able to glean much of a story from what I encountered.
My main reservation is this: I don't think that rock/paper/scissors is a deep enough mechanic to serve as the core of the gameplay. It's OK to bring it in at the margins, but it shouldn't be at the center.
Also, I was not able to use the potions or defeated enemies in my inventory; not sure if I was doing something wrong, or if this just wasn't implemented.
