The 1984 NES version is the only one of the early releases of Lode Runner to feature scrolling levels.
Japanese developer Hudson Soft – who created the NES version – made all the character graphics bigger, which in turn increased the size of the levels. And when the individual levels were no longer fixed to a single screen, scrolling was required to make it all work.
Does the scrolling make the game better or worse? Mmm, worse. Massively worse, because you can’t see where all the enemies are and bumping into one unexpectedly happens often, and is highly annoying.
It doesn’t really feel like Lode Runner with a scrolling screen, and the play area feels a bit claustrophobic as a result. But it is what it is, and works reasonably well overall.
All the classic, recognisable levels are in there. Even the level editor is present, although there’s no way of saving your creations once you’ve made them, which essentially renders the feature redundant.
