Bigger? -- no; not if you are to use Greenfoot.ask. I think the only way would be to use a separate actor to collect the input (like a dialog frame with an input box). Well, this is the OTHER way, which you probably would not want to do (put the game world in an actor and use the main world for the input -- again, like a dialog box).
