Subs Away

Confused? My arrow keys did not move me...not sure what was going on there. I had no idea how to change weapons. I don't know if I'm supposed to kill a certainb number of fish or reach a certain depth to finish the level. Level selection seemed to do nothing. I did not realize walls hurt you, and bouncing back and forth between two walls of a narrow passage is a quick and annoying way to die. Might I suggest a tutorial and/or more of an explaination?

lame....but at least it doesnt suck ass.

Tediously slow
