Definitely planning to buy this sometime!

You’re welcome!

Part of me feels like the health-as-timer mechanic was born from the developers approaching the game with arcade-style design in mind. That sort of thing works to make sure people don’t play too long on the machine (a la Gauntlet or Wonder Boy), and while other games still retained it I don’t think it fits well with the kind of game Mega Man turned out to be. (That said, I think the final product’s completely useless scoring feature is definitely a holdover from this same line of thought.)

This is an excellent study! As idealistic as this may sound, I really do hope it becomes a landmark in video game preservation - hard, inarguable numbers making it clear that significant chunks of history are missing from the current gaming landscape.
