A very cool game base that could be really good with some polish. I think the others touched on most things, but I'm going to go by my experience too: Liked the crafting and gathering ingredients mechanics, as well as the survival aspects.
I did indeed spam fish to get a lot of fish and that's hunger taken care of :D
I crafted all the parts, but after that, the Build action did nothing, whereas up to that point it told me I don't have all the parts. I'll consider that I did finish and got off the island.
Dying also seemed to do not much, since it just let me continue with all my inventory AND the next mob I would fight would be at 0% hp, so an instant win.
If you fix these bugs and maybe add a bit more crafting variety, it's going to be quite entertaining.
