Ideas I currently have, in no particular order or priority:
Page explaining the Elements, how they interact with one another (including Normal).
A Minute Frontier page explaining the game in detail (the Minute Frontier Wikia page should be used to introduce the user to the Wiki, not the game). This would incluse the save file screen, mechanins like tapping the screen, visual options, etc.
Areas (to present all the backgrounds and where backgrounds change)
Collection/Library page, explaining how it works and how they are shared from file to file
Revamp the MinuteFrontier Wiki page to display pages. As suggested above, move the materials pertaining directly about the game to a Minute Frontier page.
I don't think the Elements need a page for themselves as it takes only a few line to explain and would be difficult to redirect too. O already put it in the FAQ. However people might not look at the FAQ. I think the best Idea is to rename the FAQ as a general description page with a complete introduction to the game and then a FAQ section it might be better that way indeed. I would also add the collection to this page as there is no particular use either it does count as a general explanation of the menues.
I will take screenshots of the different areas and kms and try to make something of a "Map" page.
I've spent a bit of time on the admin dashboard added a few fun new features such as badges and others, like a map creation. I'll spend some more time on it when I'll get on a computer (on my phone for the moment) in the meantime... Have fun!
