I’ve been looking for something that can prepare hydrofluoric acid from fluorite and sulfuric acid for some time, and I’ve finally found such a game.

The idea of the game is to collect every element on the periodic table to repair your ship. Compounds with several elements won’t work - only compounds that consist of a particular element are eligible.

And how do you do that? You have to react things with each other to make new compounds. And/or you use heat to do it. Or, you use electrolysis to separate elements (I like the electrolysis reaction where salt is separated into sodium and chlorine gas). Or you use your particle accelerator gun to make synthetic elements.

There are a bunch of reactions missing (you can’t mix pure sodium and fluorine to get NaF on the spot), but there are enough to get all the elements. I had a fun time with it.
