This was just okay, but videos and such talking about it led me to expect something better. The first 15 minutes are pretty damn fun, but it's kind of just the same thing for the whole runtime. It gets absurdly hard and unfair very quickly too, with enemies frequently swarming you in a way that only provides nearly frame perfect escapes.

The controls are a bit weird, probably worked better on the arcade version, but rather than aiming with the d-pad you have each button correspond to a direction to shoot in, with diagonals working by pressing two at the same time. It's kind of wonky using a keyboard, but I don't think it seems much better with a controller (at least not the diagonals). Not that I'll play it again to find out. It may be actually pretty close to a decent game, but man it is really exhausting.
