Great entry! I would've liked to see the arrow/platform mechanic used a bit more as a puzzle element than as a replacement for double-jumping, but it's a cool little platformer with a solid concept nonetheless!
I wasn't a fan of the dynamic camera: I agree with the criticism that it goes too far based on your direction; it can get a bit nauseating! It also looks like the camera is using screen-space coordinates instead of the 160x144 grid, which makes it a lot smoother than the other elements in the game.
I really appreciated that you could continue right from where you died too!
