Lucas M. Thomas writes for IGN:
"Spelunker [is] a download that isn't really worth its asking price of 500 Wii Points at all. As a classic platformer from the early '80s, Spelunker certainly has some nostalgic value and will surely appeal to those gamers who played one of its original forms from 25 years ago. But newcomers to the experience would simply be frustrated by the control, which is nonsensically strict. It'll only take a handful of deaths coming about as a result of a five-pixel-tall vertical fall before you hit the Home Button to quit playing, and that earns Spelunker the dubious honor of joining Urban Champion, The Legend of Kage and Operation Wolf as one of the least desirable NES downloads on sale in the Wii Shop."
