Good: I can see this being a really great game. Lots of potential with ambiance and art style. Reactive controls and rolling/shooting/attacking feel great. Love the main character weapons as well.
Improvements: Either the world needs to be more interesting (deadly things to avoid while walking around) or there needs to be a run button. It's cool seeing a new area at first and wondering what you'll run into - but it goes on for a while with nothing interesting to see/do.
Look forward to seeing how it progresses!
