Looks gorgeous!! To what extent is it non-interactive though? More on the Tamagotchi side of things, or more along the lines of Mountain?
I'm a little ashamed to use the word Tamagotchi... There will be no challenge. The concept is : the more time spent with Tina, the bigger the plant grows. And that's it.
Just leave Tina.App open somewhere, to hear her say things, and do stuff.
It would be cool to "feed" the plant or something like that, but I didn't find a simple way to do it... yet.
