This one was really fun to play! Congratulations!
I killed myself a couple of times at the beginning :), but then I got the hang of it. Controlling your bullet with the mouse and being able to make if bounce off the walls is neat! Sometimes I wished I could zoom out a little because I moved the mouse a little too bluntly and I lost the sense of direction.
All in all a great game with lots of potential. Thanks very much for sharing!
