Thank you! The idea is to have more elements and more possible alloys, like brass or steel, in the future. Som puzzels (that didn't quite make it in the 48 hours) will have you pass through bronze only obstacles and then need to go back to the individual elements for the rest of the level.
We will keep working on it, stay tuned on this page if you'r interested in playing more. Anyhow, thanks again :)
