Damn I totally forgot about that :
Here's a game I worked on last year (characters, items, backgrounds, well.. pretty much everything except all the User Interface thing)
It's called "Japanese Learning" (by Tokkun Studio), released on June 7th, and it's available on iPhone and iPad on the apple store (looks like there's no android version for now).
You can see the teaser here : [link]
Actually, I do not own an iPhone nor an iPad sooo... Well I don't really know how it works huh
