Introduction to JavaScript Programming - Final Project

For this project, I have created a memory game with images from the Protein Data Bank (PDB), a database of protein structures. A random set of database entries is selected from a list of identifiers when the page is loaded.

The game does not currently include different levels, but I am thinking about including settings like different species (currently only human proteins are included) and/or allowing the user to specify a custom list of PDB entries that they want to see on their cards.
Once all pairs have been found, the cards are all revealed and can then be clicked to open the corresponding PDB entry page. The game can be restarted any time by clicking the button in the top right corner.

All code and more details can be found at github.com/cvnoort/pdb-memory and the game can be played at cvnoort.github.io/pdb-memory.
