Atom Sifting Exercise

Aspiring alchemists, has THIS ever happened to you? "Here I am, casually combining my reagents! OH NO, **** it spilled, it's gotten everywhere! ****! ****! ****! SOMEBODY HELP!" Well worry no more! You can clean it all up with a little "atom sifting": a technique seen by many as highly advanced. But fret not, with this collection of informative training exercises, you'll become a pro in no time!

This is really just a lame game about making marbles roll, but I need to fit in the theme somehow. (I'm taking lame to the whole new level!)

Oh, and this is basically just an Opus Magnum fangame. That's where the marbles come from.
