Man, it's like people here have never played old 8-bit games. No save points, no ability to continue, no password system, touch any object and it kills you, you have 8 points of health but every enemy takes at least 4 when it hits you(why not just have 2 points then and each hit takes one?), you can't change direction once in mid-air, traps are never intuitive or even remotely predictable, every new area you get to is essentially trial-and-error until you learn the pattern, and you generally consider it generous when a boss only has 10 times your HP because hey, it's usually even more.
Super Rudy Block is exactly the kind of game you would've played in the late 80s. I mean, geez, hasn't anyone played Punchout?
