I enjoyed it, though I feel it was a bit too simple and there were some situations where I was forced to take damage not because of earlier choices causing me to, but because of just a completely unavoidable event.
I think you should make all events able to be dealt with with the right resource. Also you should really clarify the importance of camping, I didn't realise until after I lost two people to an instant death event that I had to manually put in their batteries.
And I think you should make more interesting situations rather than minigames. And also make the overworld actually do something a bit more, since most of the time waiting didn't really seem like anything would happen, and it basically didn't.
Still, I enjoyed it, it just needs more meat on the bones. It's got good atmosphere.
