Alchemy. Modern remake

Ladies and Gentlemen!
"Oldschool Infundibulum Sowtware" presents to your attention the game Alchemy, which is a conceptual remake of the old-name DOS game ( Post about DOS game )

And here is a remake.

Picture to attract attention:


The controls are intuitive, but still a couple of tips:
- drag one item to another to trigger a reaction
- double click on the field to get 4 main elements
- double click on the item to clone it
- in the list above open items are displayed. Click on any of them to add it to the field.
- excess elements can be removed by placing them on the black square on the right
')
Purpose of the game: hmm ... hard to say. Probably try to get something interesting. Create a life to begin with, for example)

This is written in pure JS and, despite being played in a browser, is not an online game.
Who will spy the reaction in the source - the cheater, not the alchemist.
Best at Firefox. In Chrome, not so much; he constantly strives to select something on a double-click.
