Hey, that was quite nice!
Very short, but designed with a lot of thought. No pixel hunting, good perspective with a clear layout and not too much depth, characters do not feel like "obstacles" too much. The animators never took the cheap way out - actions of main character Bwana are normally performed in plain sight and are quite big; it helps a lot with the immersion (modern adventure makers keep forgetting that).
I first thought of the "African mask" theme as a cheapo variation of the Grim Fandango paradigm. It really isn't. There's quite an interesting application of facial expression in there, which is all the more visible as you don't expect it from those masks.
