I really liked it XD
The input in sudoku puzzle is really hard to understand at first. I think I got stuck there because I didn't do something. But, after trying I understand how to input the number. XD
The usage of plants and stuffs for the numbers also great. It makes it more natural rather than putting numbers on the ground. It's hard at first. But, after some time, I think I'm able to memorize it.
The sound clue for the puzzle really helped me solve it. XD
The story is also simple, and easy to understand. XD
