Not bad for 4 hours. A little too much maze :) I really thought I was going to make it, but got impatient and a shark got me in the upper part of the maze before the open water :(

I really like the art, if there just a little bit of other gameplay this would be much better.

Not bad for 4 hours! I agree with George though, there was a bit too much maze. If you wanted to develop it further, I'd recommend a smaller maze with more hazards, and smoothing out the controls a little bit. I often got hung up on the last pixel of corners that I'd thought I had already rounded.
