Very nice graphics, especially the outside area with the crows looks nice. I also liked the funny dialog with the kid and shooting some crows :). I think I did not fully get how to play the game and how to win. It would be nice if the yams you plant could be harvested on the next day, but they seem to disappear. So I was not sure why I should plant them. Additionally, I experienced some glitches where I just picked up yams, without seeing one. For example at the door, but sometimes also in the field.
Anyway, I think it is a nice starting point for a fun game! Congratulations.
