This is a showcase using my custom list-based variable engine. This engine can make, delete, or get any variable with one block. No need to create variables manually. 200,000 variables can be made due to Scratch's list limits. Keep in mind, if you make a variable with the same name as an already existing one, it will change the existing one instead of a new one!
Press Space to see this in action! If you want this in your project, backpack the first sprite. NOT the "showcase" sprite. A user guide and how to use is commented inside the sprite, with the custom block examples at the bottom.
