FYI, the Linux download you've got here isn't a ZIP archive...it's a tar archive. You should rename the file to:
midnightcreak_linux.tar
...to reduce confusion. Alternatively, since it's just the one file in there anyway, you could instead just gzip the executable itself and distribute that as:
midnightcreak_linux.x86_64.gz
...and skip the middleman. :) As far as the game itself, it ran perfectly fine (I just finished playing through it)...it's just the name of the file that needs updating.
As for the actual game...good job! I don't normally go in for this kind of game but this was tense enough to keep me on my toes but not so much that it felt psychologically exhausting to play.
