Gameplay is outstanding fluid and complete - well done! It's a perfect example for how to scope a games mechanic just perfectly right for a given, short timeframe.
Same goes for UI and graphics - they are as consistent as the whole game loop. And having everything ready for mobile interactions is also a big pro!
Music is meh...
Haven't encountered any bugs, just some minor irritations: The Buttons for adding water or a glass house confused me - I was sure when clicking the "sun" icon some sort of heat will be added, same for the snowfalkes - supposed to add some cold. After first mistake, it was clear. Maybe change to a water drop and an icon for "cold protection" (a shield with a snowflake on it, maybe?).
It might be a good extra challenge if plants would die if their needs are not satisfied.
All in all really well done!
Last not least: "Carrots, anyone?!"
