Erik and I played through the first world of Cuphead. The gameplay is a solid Contra-esque boss rush with a few scrolling shooter stages in between. It's super hard but fair, and the graphics is astounding. It is a bit buggy, though - the game crashed right in the beginning of the first world, and sometimes getting hit will result in a controller permanently vibrating until the next hit. If only you could disable rumble. Maybe there is a Windows option to do that?
