1107 - I knew I must have done something right when my computer slowed down to a crawl :D
Really enjoy the concept, creating a complex reaction from very simple initial conditions. the game rewards a bit of experimentation but maybe it would be cool to start small and then scale up to learn the basic rules of interaction in a more intuitive way, starting with 60 seeds(?) makes it a bit tricky to follow what's going on initially. But the reaction is mesmerising, very cool particle effects! Like the graphical style and calming music, very nice!
