Please use the number key of keyboard. I created the program of text box, because I wanted to show text dynamically in scratch. I will use this method for my games in the future. Of course you can use it. It takes a long time for loading, and creating clone is heavy. I guess because it uses many costume for char. It will be lighter if it doesn't have the color change function or many characters.
Japanese version http://scratch.mit.edu/projects/15543986/ I found below things. - Creation of clone is heavy - Stamp is lighter than clone - The number of clones on the screen at the same time is 301. - When the setting 'run without refresh' of definition block is valid, It should not have any waiting block like a 'wait until ~~'. It causes slow down. - List can be used to give many parameters to another sprite. - Variable is faster than List if it is used for waiting block.
