I haven't got very far into it and with there being no save I need to give it some time before I can properly play it to give my ratings for the game jam. Therefore I can't really say much about the storyline or puzzle yet - did at least manage to find all the bits of the torch and make that though! ;-)
Impressions so far though - graphics are really well done, the environment layout is good, and the ambient SFX are really well done. Hoping to give this a proper go soon. I struggle a little with large environments that aren't very interactive, but appreciate that you wanted to convey a feeling of emptiness, at least in the beginning section (I'm not sure what you come across later!).
Oh one more thing - don't know if it's just me but because of the graphical style and control methodology, I constantly expected to be able to jump by pressing spacebar! :-D
