This is amazing! It makes me feel bad that you are getting a bad score because the game does not have an English translation for the words and buttons.
For anyone playing that is confused by the game, essentially you are a shop keeper at a nursery.
On the left is a customer, and they are telling you their order.
On the right, pressing the yellow button passes some time, and gives you a random item.
Move the items into the middle onto the "board". Seeds go into pots, and the plants require water to grow. When they are done growing, drag them onto where the customers request is.
You can buy a pickaxe for some coins for the rocks.
Pressing the red button clears everything inside the little 5x5 board.
I hope this explanation helps some people who are confused by the game, give it a chance, once you have a lot of things on your board the game starts to pick up and be a lot of fun!
