What was meant to be a puzzle game became a very tiny sandbox where you can make things explode and stuff.

[Left click] adds a particle on mouse

[Left hold] adds a stream of particles

[Space] randomizes the seed for chemical bonds (default settings are hand-crafted and most stable.) -- You can also edit the seed manually in the upper left, 24 for example seems to be a pretty stable one where the stuff barely reacts with each other.

[Q] toggles metaball thresholding

[G] toggles gradient for new particles

[Any other key] deletes all particles

I love the gifs, but is there any chance for the linux version? That would be amazing!


Unfortunately not natively at least.

There's a chance it runs in some of the ancient flash players available on linux (11?), or the exe on wine/etc. Haven't tested either though.
