Once you get over the learning curve of the controls (it actually feels really good for 85), you'll find an early example of a precision platformer that treats you like an adult, requiring mastery of its (frankly limited) systems to succeed. You'll be repeating the first few screens over and over, but you'll find yourself getting a little bit further with each attempt. Just don't focus on beating it as quickly as possible, a perfect run is only about 20 minutes long. It's truly the Dark Souls of platformers ;)

Seriously, give it a go. A complete run of the first loop will take a while, but it's really not as intimidating as it might initially seem. There's a reason this game has stuck in the minds of Japanese game fans. I would have been all over this if I was a Famicom owner back then.
