Really nice game! I enjoyed the music!
I loved the narrrator/character! It would be nice to be able to adjust the sounds but other than that awesome job!
The game was really fun!
For example it would be nice to lower the background music or the general sounds (like shots and zombie's screams), that way it would be easier to hear the narrator/character, because sometimes I didn't get what he was saying. That's just a minor detail that would be nice to have in the future, other than that the game is really good.
