Make a script:
- {l Code}: {l Select All Code}
Level.finish(true)
But this will return Tux to the worldmap instantly, so I recommend something like this:
- {l Code}: {l Select All Code}
Tux.deactivate()
Effect.fade_out(1)
wait(2)
Tux.activate()
Level.finish(true)
And no, you don't ask too much. Rather ask one time more than deliver something you are unhappy with.
