I liked this more than I thought I would. At first I was annoyed by the small field of view, but as the game progressed I started to enjoy it. In the end I had a kind of mental map of the game, which made it surpisingly doable to search for hidden corners I had not visited yet. It is a kind of maze game really. I also liked where the end was hidden! It was exactly where I thought it might be :D
The only criticism I can give is that the buzzing sound when you died was a bit jarring to me. Otherwise, really well done on this one!
