Reminds me of "Chuckie Egg".
Similar games are also Goonies, Montezumas revenge (aka Panama Joe on Spectrum) and Lode runner for those who are interested.
BTW played Chuckie Egg on Spectrum hours and hours back in the days.. was really hooking game with such a simple concept. Also loved Panama Joe to death... hmm.. me'thinks its time to fire up PS3 Speccy emulator when I get home :lol:
