You might want to remove the bomb, because you can play indefitely if you just hold up and click around on the screen with the bomb. (For me the progress bar actually just stopped moving because of my constant movement)
It kind of adds to the challenge, and I also had the idea that it then means that you need to decide to play it safe or risk it and go further everytime you get to a safe area.
I tried to make it way to hard, and I also joined way to late, so I didn't have time. I can tell you it happens every five seconds and lasts five seconds. I am thinking about adding a visual cue to alert you to wind in the future.
