Waller is evolving.
It started off as a quick and simple demo and now is undergoing massive refactoring as it's adapted to game development needs (it's being used for development of a first person, dungeon exploration oriented, oculus rift enabled, awesome game :D ).
For this reason, while the Tiled Map loading stuff is still here, Unity functions are being removed, and will probably spark a whole new project on its own. Shortly (as soon as i'll get some spare time to housekeep) a simple demo will be placed back in current project, while here in the readme you'll probably find a pointer to new goodies. Enjoy!
