I am now working on a small new FPA for the Myst Jam hosted on itch.io (here). I have to release this game before January 18th, so the development of Catyph is paused until then.
Myha will be a free game of course, and will be created in special circumstances, so don't expect it to be a new amazing adventure game that will bring new ideas and gameplay. It is first created as a tribute to Myst, according to the rules of the Jam, and will feature old-school graphics and gameplay.
You can follow the development of Myha on this forum.
