This game makes me feel... panicked. You don't really get any respite in particular levels, since your shadow is always half a second behind you. You can't gain any ground, either - which makes it so that one mistake at any part of the level results in death.
It's a very punishing game, which can be fine. I agree with previous commenters that a quicker restart would be useful, and would make it much more palatable to try and re-try.
I did enjoy playing what I played. The spritework is decent, especially for the cloaks and the torch. The tileset would be great with a couple more shades, more detailed brickwork would add a lot.
I think there's a good core here. It just needs some tweaking.
