I ended up playing all the way through and really enjoyed it!
Maybe could use some quest markers? Because it was surprisingly difficult to figure out that the peppers were in the bushes, but on the other hand, that did force me to explore the island a lot.
I see that you added some changes from Roldy's suggestions, because I got a lot of use out of the auto run button.
It was a lot of fun to see the water rise throughout the game and my only regret is not blowing up the boat before I left.
This must have been a ton of work by yourself, so take some time to relax, you deserve it!
