This is so, so awesome and Indy-like! Love the theme - really Montezuma's Revenge-esque! Question: Would it be totally out of place to please ask you to consider a native Commodore 128 port of Jungle Joe? It doesn't have to feature any extra bells or whistles at all - in fact, I'd go wild just being able to type "RUN" from the BASIC 7.0 prompt to start Jungle Joe.
Why? Well, the Commodore 128's games collection is so small any addition to it would be a huge boon, and a clear sign of good-will to the Commodore 128 community. I'd be most grateful if you would consider it, not closing any doors. Having an Aztec like platformer running natively on the C128 would be a feat and an acomplishment all of its own! Crossing my fingers and hoping for the best!
