So instead of making individual pages about individual levels, I put in a list of possible combinations in the Gate section. The colors of the background and icons are done. Now we just need to elaborate on the icon itself.
To clarify: The type of levels that Knights will play! The majority of the levels have been documented, but they lack a lot of things. See Clockwork Tunnels for an example.
And I saw Maget uploading gate icons and now I feel bad because I picked the worst timing to suggest this D:
Heh, you beat me to it. I started to single-handedly work on this just yesterday, and posted my suggestion in the Gate Construction Formula thread :)
