This basic Scratch game starts with a maze that must be completed in one minute or it is 'GAME OVER'. If the first maze is completed within 60 seconds the player goes to Level 2* and another maze that also has a time limit. If Level 2 is successfully completed the player is congratulated on reaching Level 3. However, there currently is no Level 3! The player is invited to create their own Level 3 maze as a backdrop and so develop the game. *The Level variable has no coding. Yet... (See the 'Notes and Credits' for a suggested way to add more levels.) As with other platform games it is possible to add further sprites that threaten the existing sprite, rewards or 'lives' could be created and points scored etc. Note: If you change the sprite's costume you should be aware that a black outline might interfere with the walls of the maze - and don't make the sprite much bigger! Develop as you wish. TIPS (not exhaustive): If you use the suggested web site in the 'Notes and Credits' and follow the instructions you will start and finish each maze in the same place unless you are planning to change the coding to reposition the sprite at each 'level'. NOTE: in this version there is no need to 'colour in further walls in the maze because the sprite recognises the black walls and doesn't pass through them.
I used https://www.mazegenerator.net/ for this not-for-profit educational game. I selected a rectangular maze: Width 16, Height 12. Because the generated image files are relatively small I chose to download an A4 PDF of each maze then paste a screen shot in to Paint. Then I cropped the maze, turned the maze in to an image file and uploaded each one in to my game as a separate back drop. So far there are just two 'levels', with two further backdrops: one congratulates the gamer on reaching 'Level 3'; the other - when the timer runs out - announces GAME OVER.
