I loved the idea of this game! It is educational and is a nice twist on resource management.
Sound: playing via webgl and not hearing music. The end of round sounds are a bit jarring and don't seem fitting with the nature theme.
Visuals: I enjoyed how the trees/bushes responded visually to being harvested.
Gameplay: It feels like the player movement could be sped up a lot to make gameplay more enjoyable. It feels very slow and sluggish right now. A brief popup displaying controls would also help - the red box was confusing at first.
