Game runs fine, controls work, there is no audio!

as title says , i have recettear but not the other two thx

I rarely finish games anymore so I'm more into playing games with achievements. (Plus my Steam collection has grown too big when it comes to beating everything...) When was the last update? Just wondering if there's any chance for this to support achievements later on. There's also possibility that they can't be implemented due how the game was made. Any idea on that?...

Are the save files for this game located somewhere I can easily access? I've been thinking of getting this game for a while, but I noticed that it doesn't have support for cloud saves...

Can someone give me some details about the game?
