Did it and my hands actually got sweaty in the process. The good ole days of sweaty hand and controllers, lol, the two must be one!
There were a few patterns that were a bitch, mainly the sonuva bitch boss that throws spiders (That bastard pissed me off), the rolly polly guys that can glitch jump whenever they feel it necessary through walls or magically 20 miles in the air and the damn hawks on the last 2 stages until you realize their pattern. Gotta admit the last boss had me stumped till I figured out the way it needed to be done.
All in all a really good challenge as it really shows the frustration us NES gamers went through in the day with respawning enemies and glitch ass shit lol. At least this game gave you continues though!
