A game I used to love is Battle Cats, a tower-defense game where you deploy a cat army in order to protect your base. Battle Cats makes use of a mixture of both interaction arcs and loops. We see this interplay occurring through each level, where the premise of beating the level remains the same except for added difficulty. Moreover, if we zoom in, even within each level there are interaction loops when it comes to unlocking characters and learning how to utilize them. Battle Cats builds off of the most simple cat fighter provided to you and its main mechanics in order to create compound interactions and more intricate cat fighters so you can beat more difficult bosses as you progress. Each cat character is also an example of an arc, as when they are introduced they provide evocative content for the player. This whole array of cat characters builds a sequence of arcs.
