Nice game! We had a very similar idea, and it's fun to see a different take on it. I liked the little action log, but it was a bit hard to follow so I had trouble keeping up with what was going on - for example, when I first noticed my health was dropping, I couldn't tell if it was because I was missing items or because something had happened in the action log.
Scoring by the item value was neat, and I liked how I could juggle items to buy a little more time to think.
