There's not an actual guide on how to do this specific game.
What you need is break it down, guess how it was made and implement it in C2.
To do that you need first to be comfortable with using C2 and what programming tools it brings you. This is done by reading the manual, the tutorials and making small examples/experimentations/games first.
A quick analysis, it's basicly a match game, you input two "elements" and see if they match, "unlocking" a new element.
So "behind the scenes" you probably have arrays containing the datas for the elements (what other element the actual element mixes with and what element does it gives).
Checking the examples in the how do i FAQ
in the sections "Arrays" should get you a level start about arrays and how to use them.
Keep reading the available tutorials and experiment, this is the best way to achieve your game.
Also moving this to the "Game design" part as it is not as much the different breaking of the mechanisms that you appear to be in need of than how to technicaly implement them.
