For those that are curious as to what Métamorphose 2 will be like, a pre-alpha version has been released.
While most things work, there are of course a lot of unfinished portions and numerous bugs. I would not recommend using this version for anything other than testing and evaluation.
If you do evaluate it, please post feedback regarding the interface, features you would like to see etc.. However do not post bug reports until it reaches the beta stage.
