An example of the Pixi ParticleTest demo with basic time travel

pixiparticletest.html is the basic Pixi ParticleTest demo

pixiparticletest2.html separates the the dude and sprite structures, the dude structure is updated each tick, and a view() function applies the changes in the dude structure to the sprites

pixiparticletest3.html moves the update of the dude structure into the view() function - the information can be calculated parametrically based upon a seed and a time value. For time travelling we store the seed and the t each update, and we can recreate the historical state from these two values.
