posted an update (Windows version only right now)

this update includes a proper menu title screen (at last), and several tweaks to many of the existing maps to add more secrets, and secret mechanics, inspired by THIS excellent video: Deconstructing Mario: How Super Mario 3D World hides its Secrets and encourages Exploration (by Ceave Gaming). there's even a whole new map that acts as a shortcut between two other areas, with new enemies not seen in other areas of the game.

I've also started work on The Red Isles, a (non-secret) area of the game which is going to be one of the major legs of the main quest. very little is done there, but feel free to poke around :)
