Tired of not being able to see when your crops will need watering next? I am too...
What about a little icon appeared above the crop when you hold a watering can?
The icon would slowly disappear as the water is soaked up by the plants
example - full icon when just watered.
6 hr later the icon is half gone
12 hrs later the icon is gone and replaced by another icon symbolizing that you need to water your crops again.
How would this help?
with this you could easily time when you need to water your crops next, allowing you to make a perfect schedule for your plants :D
