It was made in just a week, so it's real janky and limited, but it's kind of addicting and really hard. It's likes to screw you over, but each time you get a little better at it. Also, it has all these fine controls for gun handling that make you feel like a boss when you master them. Still haven't finished it, but every so often I come back to it and try.
