Ah I found the problem. I have winrar and it automatically used winrar to open it.
About the game: Its extremely stressful with just 1 second. I found that jitterclicking your way through is the way to go. There should be a little penalty when you get something wrong. Also, next time, to give the player some slack you could make it a little more then 1 second.
Overall it was really well polished. Good job.
