Skit Maker is a feature in Gacha Life that enables you to make up your own scenarios involving the different characters you create in the game. Although the Skits you make can have up to 100 scenes you can only have up to two characters on the screen each time.
When you make a Skit the first thing you need to do is choose what position your characters are going to be on the screen. This will be a character on the left and one on the right. Speech bubbles can then be added to each of them in the white boxes in the middle. The options to change the background of your Skit are on the right side of the screen along with the character facial expressions, and poses.
Once you are happy how your Skit looks you need to change the Max Lines from 100 to the number of scenes you created and then tap the 'Test Skit' button at the bottom of the screen to watch how your creation unfolds. Remember that if you tap 'New Skit' you will delete all the lines you have created in your current Skit so make sure before you proceed and create a new Skit you don't mind deleting the old one
