This mod for Spelunky is messing with my head. It's a mashup of two games which each have a highly specific, distinct gameplay feel. I almost can't deal with seeing Samus so zoomed out.
To achieve the desired effect, creator Joey4track reskinned the original sprites and swapped out the music to recreate the look of Metroid. But this is still very much Spelunky in terms of how it handles. There are some inconsistencies -- ropes and dogs, for instance, appear unaltered -- resulting in a creation that is weird and cool, all the same.
