Fireworks to go lets you spawn fireworks and fountains to your liking.
Just tap anywhere on the screen to shoot a firework rocket to that location.
If you tap for a bit longer the fireworks will spawn extra crackle.
If you tap near the bottom of the screen you will spawn fizzing fountains.
If you tap for a bit longer the fountains will be higher and larger.
You can spawn as many rockets and fountains as you please and your phone can handle.
