I have localized Alchemy to Romanian and Dutch and implemented live preview when dragging elements across the desktop area. Button Wikipedia was replaced with a language button. When you click it a new window pops-up displaying a list of available languages.
The game language changes immediately. However, since the two lists with the elements are sorted alphabetically, when you change the language, the order of the elements in the list changes.
Special thanks to Ruud van der Eem who translated Alchemy for Dutch.
If you want to help translate Alchemy to your language, drop a comment so I can contact you.
