4/5. I still don't know what's going on in the game, just that I don't know how I got here (the character, that is). I'd like to see more of a story line, more interaction in some fashion. Better UI would be nice. However, I do like the pixelated, Nintendo feel to the graphics.
The game play is nice, a bit easy - but that lends to the Nintendo feel again, so it works.
The 4/5 is because I would like to see more to this than what I've seen thus far. Like I said, more of a story, better interaction. Things of that nature. As it is, it's nice and I enjoy playing it, but I'd love playing it with just a little tweak or two.
