philthethrill10, thanks for the news!
I have been looking for this game since it came out in 2015 as a DVD supplement to some Hungarian magazine, and the authors could not tell me how to get it.
So, they have finally released it for free, which is just great!
No, I do not speak Hungarian as well, and yes, they did tell they are working on an English version, - but it is so long ago that they were going to do that, and to release 'Youmurjak' on PC again, and to make the new 'Agon' game... No news since then unfortunately - so it's nice to have at least this version available.
I have downloaded and installed 'Miazma' without any problems!
There are 5 .sfl files in 'Game' directory, yes, but you can launch the game via the link or by miazma.exe in the main folder.
