If you have watched my course about Using Shared Actions, you'll already know that this is one of my favorite features. It makes it possible for newbies to create rather complicated tutorials without need of programming skills.
I already uploaded a game recently, here is another one. You can use this link or play with the embedded one:
It was created with SVGs (thanks to Illustrator), one shared action, two advanced actions (which could be converted to shared actions as well), Drag&Drop features, multistate objects. The setup makes the game very flexible. In the example sequences were all with 6 shapes, but you can create them with any number of shapes. You would have to find a new indicator for the degressive score if you have more or less shapes. The adult version can be converted to a kid's game, by using easier sequences
