Hello Templar and thank you very much for your comment and your nice words!
I'm taking great care of every aspect because it's a labor of love that the Amiga deserves for being the spark that ignited my creativity :)
I've tried to add atmosphere with an engaging story to keep the player interested, there are also some fun dialogues and references.
My idea about music & sounds is to use the music only on the title screen and in the menus, during the game I planned to use only sound effects, looped sounds for machinery and simple tracks during boss fights to add tension.
I planned to deliver the demo to a couple of friends before the public release in this week, but my TV has blown up so I'll have to buy another one...
As for additional languages, yes, it's possible if the game is well received.
90% of the game data is in external files and therefore easily editable.
...furthermore, I have a lot of ideas in mind for a possible sequel :D
