I like the floating bobbing boat and boxes, they look pretty cool. I am guessing the underwater squares will get some seaweed and fish and not look like a checkerboard.

First aid kits, magic fix the legs, one shot and walk, but where on the island can I crawl to to get one? Maybe magic poultice to make from weeds, or better yet magic mushrooms they solve all sorts of problems.

I like the injury concept. Makes it more real. Just so long as the recovery time is not to real, like 6 weeks for a broke leg or how ever long it takes to recover from a broken bone.
