Strange...
I don't know if it only happens to me, but I can simply let the submarine drown forever, not touch any button, and the game will never stop.

This game was made for the Adobe "Made for mobile" contest. It can be played on a Computer or an Android phone (or any device with the latest version of flashplayer). Let me know if you're one of the people to try it with an Android device.
Too small of a playing area.
Which meant I had a hard time seeing what was coming up. and it wasn't mentioned that you don't HOLD the Up or W key, but instead tap. That bit of knowledge would have saved me my first three or four deaths.
