We added some bugfixes to the demo version on Mac/Linux. There were some files that were being referenced by names with a different case than the actual filenames. 

We've also changed the save file location. Previously the save files would be located in the game directory, under the save folder. Now they will be located in your home directory (e.g. "C:\Users\Username" on Windows) under a folder ("echoedgames/gmem"). You can copy your existing saves to this new location.

If you find any bugs, please let me know at https://bitbucket.org/Echo607/gaias-melody/issues?status=new&status=open
