Want to add more levels?

We'll need to create a new set of variables and put them into action

So watch carefully . . .

  Remove the “winner” script from the shark

  Create a variable “level”

  Add this code to the script for the stage

  It works by setting the level to the score

Setting up the levels

Changing the maze

  Create a new costume for the maze called maze 2

  Create a new costume for the maze with a win message called end screen

  Include this code in the maze scripts

New prizes for the new level

  Draw or import a new prize sprite

  Create a new costume for the maze with a win message called end screen

  Include this code in the maze scripts

A bit of tidying up . . .

code

Pimp and personalise your game . . .

  Add more levels, see if you can make then harder

  Set a timer for each level

  Use the pen scripts so that you hero leaves a trail

  Create instructions, a start screen and story

  Add or create soundtrack for your game
