Congratulations on your first GWJ and your first completed game. I think you did an excellent job! The game fit the theme perfectly. I enjoyed the atmosphere of the dark cave you were able to create. The last level really felt like I was getting to the mouth of the cave. I found that the controls worked well for me and didn't have trouble getting through the levels. I agree with the other commenter about wising I could go fullscreen because I really liked the art.
