Some bug fixes

It was hard to sort the words so there is a easier word sorter.

Walking through the maze show the words you are about to collect. Still not greatly done but in line with https://godotengine.org/qa/10913/text-object-in-3d-space?show=88565#a88565

The credits was missing the right JSON file so now we can credit Michel and Coma too.

And the resource used are known too.
