I totally loved the concept of this game! Crying is healing. Healing creates space for happiness!! First of all games that talk about mental health straight up conquer my heart! This game has a wonderful concept of letting your tears flow as a part of healing from your wounds. It starts with the main character called Noona(elder sister in korean) and you learn to simply tap enough to grow your own happiness tree!! The graphics of this game is very simple but they can still improve it a little bit or  add more visual effects. The music is relaxing and the gameplay is smooth. Some icons and instructions on the screen were a bit difficult to understand initially but later it got clear. There are several boosters that you unlock that increases your healing power. Also some fairies play their role of helping you heal.It all goes around this healing concept with many encouraging sentences popping on the screen that talk about normalizing crying. Although I played many tapping games and this one had a similar gameplay, I loved the way they provided quite a lot rewards(achievements). With these rewards you can upgrade many things that can help you in the game. It was very easy to progress in this game !! And the feeling of seeing your happiness tree grow is beautiful!!! While as a whole i loved this game, I felt that such games may not be suitable for everyone. For eg, a person who is completely happy in their life may not find it very entertaining. So that kinda blocks some type of audience. For those who are in their healing journey may find it very good!! Other than that I always feel tapping games should not extend for a long duration since the game mechanics remain the same even if you provide many visually attractive stuffs!! So ideally level 500 appears a decent number to end it. Inspite of that , it was a great game!!!
