Blueprint + Cascade Fireworks system for my peeps!

Is there a link to the updated version? Looks awesome, great job!

Hi;
In the Level blueprint I found the keyboard keys [1,2,3,and 4] were used to run each one of the fireworks for one time…!!
My question is,
How to run all the fireworks for ever, as soon as I play the game inside UE4 Editor…!!?
Thank you
