It was a very soothing work! The background of the game screen and the cards are very elaborate. As for the difficulty level, I thought it was a little difficult to max out all the meters, but I thought it was easy because I could afford not to take the disadvantage of redrawing cards, so I could play cards indefinitely. But I feel like the game is in a better state now where I can relax and play with lots of cute cards while relaxing, rather than increasing the difficulty level and getting frustrated with the difficulty. Also, I think the message when you clear the game is special and made this game memorable.
