Apologies, this was our first time and we're both fairly new to game design. The idea was it was a capsule put over top of the planting area to show that it was growing, orange was to show it was done. A visual timer of sorts.
We will be pushing a new update to this game as we've decided to keep working on it. The capsule is replaced by actual growing plants. Sounds and more line will be added. Check back in the future to see what we've done!
