After a lot of on and off tinkering, we've finally got fireworks! Several different kinds, in fact, and you can pick which ones you prefer to have available. In addition, select from a collection of appropriate backgrounds or select your own custom image.
Fireworks also allows you go vary the intensity in a few different ways. You can turn up how often a firework is launched, or increase the odds you'll get a burst of a whole bunch of them like a proper fireworks show would do! You can also set off a firework in response to touching the screen, or enable a halo effect around them as they burst!
Hope everyones like it, and as always send over feedback if you have some. :)
