Insomnia: Theater in the Head

As the name suggests, it is a game depicting the feeling of insomnia, whose plot is revealed through the exquisite hand-drawn paintings of KeKe, the chief artist of "A Perfect Day".
Hickory dickory dock. The city's deep in sleep. The clock's ticking. The sheep's bouncing. Hickory dickory dock. The girl flips on her left side for the third time in the night, only with more things swarming into her head... Well, the show in the head is rolling on again. Is it possible to get some sleep tonight?
It's deep in the night. Have you ever been turning and tossing in bed? It's late in the night. Have you been turning and tossing in bed? Are you sad, worried, stressed, anxious, or confused? Did any negative emotions from the day affect your sleep? Or are you simply sleepless?
Anyway, we hope you can enjoy good sleep every day after playing this game!
