Are you trying to play on your phone?
I am aware that fishing stopped adding fish.
The Jam or Jelly game is not easy to figure out even with the instructions. You need 15 of the same fruit and a glass jar.
What do you mean by black box? Don't think there is one in the game.
Planting things is a lot easier on the computer. I tried planting stuff when playing on my phone and see that it needs to be improved a bit for phone play. The plots may be to small for phone play. I only got one to work so I can increase the plot size so it can acknowledge finger touch.
I play tested PC version and it looks like I need to fix planting
