This is a demo of the particle effects engine in gravity.inked. If you have an Android device check it out.
Preset Effects are particle effect combinations that are already built into the game that you can choose. If you're not into a bunch of fiddly options then this is where you want to stay. All of these options are also available in the gravity.inked.
Play with all of the sliders and options to create your own effects. Use the permalink to save your favorite combinations. The same customization options can be unlocked in gravity.inked by playing through the levels.
Thanks to Ben Prunty for creating some amazing music for us all to enjoy. For legal reasons I can't use the FTL soundtrack as the background music for my game, but if you open it in another tab and play it I can't stop you either. :P
