Your page looks to describe most features pretty well (i probably just didn't read it ^^').
What I think could be improved is labeling the inventory as such, since i thought at first that every slot is the chest. Also as soon as you have about 2-3 ranged weapons there is no longer any danger in this game. Maybe you can counteract that with enemy variety or a bit more complex ai.
But of course all this is not that easy within 48h. Those are more my thoughts on how i (as a guy without experience in game dev) would continue development.
