Story
Once upon a time, there was a little penguin named Pen Pen. While Pen Pen was taking a walke, he was suddenly enveloped in a dazzling light and warped to another world. WHen he came to he realized that his one body had been split into two, and he had to take all the medicine in time to combine them back together.
How to operate
Move the blue Pen with the D-pad on Controller I. The red Pen moves in the opposite direction to the blue Pen. Move one up to move the other down, move one right to move the other left, and so on.
Then, take the potions (inkpots) at the same time. When you have taken all the potions on the screen, a space will open up on the center wall. Combine the blue Pen and the red Pen in that space to open the Screen Clear. Clear 10 levels to enter the ending. It is based on Binary Land.
There are enemies too. If you touch a crab, you will die, but if you touch a bird, the blue one will be replaced by the red one.
When the game is over, you can continue by shouting into the microphone while pressing A and B on Controller II. There is also a stage select function, so try looking for it.
Game mods
Even though it is Family Basic v3.0, there is very little memory remaining, so major modifications are not possible, but you can try making your own original levels.
The face is made up of four blocks of one character, and four characters (sepearated by commas) make up one line. Each character runs from 0 to F and corresponds to the number 8, 4, 2, and 1 in the four block on the left. If such a block is present, the corresponding numbers are added together and the resulting number is converted to hexadecimal.
