Around 9 hours 10 minutes to beat. Great game. I stretched out this playthrough over 5 months , so that may be why it took longer. Its easy to forget the more subtle mechanics with frequent breaks. I also didnt have access to the fixed aim which allows you to stand in place and aim, rather than moving while shooting. This proved super useful in the final stage where I finally gave in and used the Pro controller for the sections where I used fixed aim. I switched off to the much better M30 controller for the rest of the sections. The 8bitdo M30 has fixed shot mapped to a face button so it would be very hard to utilise on that controller. The main issue with the pro controller is the very inconsistant Dpad which means alot of extra diagonal inputs. The buttons are not great either.
Lost continues were edited out for this video. I show deaths but only within successful continues where I beat the stage. This game has infinite continues. There is also a stage select which lets you jump back to whichever stage you left off at, if you shut it off.
