The atmosphere is good. The jungle setting is pretty compelling, with the "raw", organic sounding music complimenting the photosourced tileset very well. Like Violet said, good layer work. Didn't care much for the letter box to be honest.

One thing that this needs is to break from its influences. The TR2 (and FSP, to a smaller extent) inspiration, or however you wish to call it, is more than obvious, and people will compare your pack to that, primarily negatively because of how good TR2 was. This area needs work.

How new is this coin concept, exactly? It seems basically like FSP's (with the small bonus of a 1up - again, TR2 influences). Not sure what to think of the double entrance to the temple, too, what's here right now doesn't really encourage backtracking.
