Ok, new version is up with the following changes:
v0.7.0
* New algorithm for SSR. I suck at SSR, so if anyone out there can let me know if it produces completeable maps it would be much appreciated!
* Added drop-down to allow selection of colour depth, defaults to 64.
* Changed width and height sliders to allow a min map size of 696x696 so people can make tall thin maps
* Changed width and height sliders to only allow selection of valid values (multiples of 8 etc) rather than fixing just before generation.
