Wasn't able do finish the game yet, but i think i was pretty close (only food or oxygen missing?).
In the end, what was missing is sometimes bugged, also the medicine thing sometimes works and sometimes doesn't. Also I'm not quite sure, if you will ever find a survivor? The text in the end always(?) shows you lacked of food, even when this was absolutly not the reason...
*SPOILER*
For those having problems with the electricity: maybe the alien biomass can help you (for that, just read the reason for your death :-) )
