Better pixel art and enemy/level creativity than 5, but the game design is just monotonous. Without infinite continues the game would be nearly impossible, and it's just not fun to spawn and die every 5-10 seconds, slowly grinding through the majority of the playthrough. Would love to see a re-think of the formula that redesigns the challenge, projectiles, hit detection, and control to suit home play rather than continuing to pretend that the target audience is quarter gobbling at arcades. Does have one of the coolest vehicles/set pieces in the series though.
