 A small extension that adds collision to a sprite based on a tilemap image! This is a pretty advanced extension and there is no documentation or examples, so it is recommended for advanced users only. Adds a `Moving Platforms` category to the toolbox.

+This extension provides blocks to use calculus, linear algebra, cryptography, exponentials and logarithms, and dealing with trigonometry. Also, the calculus blocks look incredibly funny so I recommend checking them out. This extension adds five categories: `Cryptography`, `Calculus`, `Exponential/Log`, `Trig Modes`, and `LinearAlgebra` to the toolbox.

+From the creator of the amazing `bettersettings` extension, @sargedev graces us with `betterarrays` - adding **over 60 blocks** to the `Arrays` category in the toolbox, (or the `arrays` namespace in JavaScript) designed to help you manipulate arrays in MakeCode Arcade, reducing the redundancy in your program of manually implementing these methods yourself. Check out the forum post for extremely detailed documentation. (scroll down as blocks have been added)

+Looping and tracking the playing of songs in MakeCode Arcade is made easy with this extension! This adds a `DJ Arcade` category to the toolbox.

+Like the sprite data extension, this super-helpful "tile data" extension allows you to store data such as strings, numbers, booleans, etc. to locations in a tilemap. It adds a `Data` section to the `Scene` category.
