Press the green flag for the sine to play. There's nothing much to say here.
The game works by putting one variable into an endless increasing function, then putting it through a sine operator. This value is then applied to the cat's "y-value" as seen on the screen. I am currently a new scratch user, but I have previous experience with Lua and one other block coding platform. UPDATE: I changed it from "Sine Tweening" to "Fixed Sine Tweening" since this project cannot be interacted with.
