It seems like it's hard to find all the islands. The gulls are a nice
touch, but even if I keep to the middle of the screen I can go by an
island without ever knowing it was there. You might want to ensure a
little more water is generated. If I efficiently hit all the islands, it
doesn't seem right that I still die of thirst.
It's tedious clicking the crate and clicking to get everything from it
when that's all I'd ever do with a crate. Maybe it would be better if
you auto-looted crates you stand on.
