A classic and severe one-button run game.
All the player can do is "press the button to jump" and "press and hold the button to make a long jump".
The trajectory of the player's actions is converted into Morse code, with short jumps being represented by "•" and long jumps by "ー".
It is too difficult for a human to clear this stage, but if the player continues to operate the game so that the Morse code is converted to "I AM SO HAPPY."

Even if you are not happy, you have to say you are happy to survive. It's just like modern society.
