Only thing I would recommend is find a way to get your sprites not horribky stretched out and blurry / bilinear filtered. Other than that the gameplay itself is fantastic.
I've noticed all of the comments for this game are sarcastic or commenting on how 'boring' the game is, but I honestly thought this game was beautiful, and the statue spirit made a sacrifice to protect humanity. It waited hundreds of years to grow trees and plant things all for us, without getting anything in return. Think about that.
