Really fun game, took 87 days to escape, 96 days to complete all upgrades, and 101 days to explore the whole island. I think a tutorial is definitely needed though the others have already told you that. It also wasn't clear to me at first that the trees with hearts (or whatever you called them) could be defeated to open up a new passageway, and the dead ends could be made a bit clearer, I wasted a lot of moves walking into spots I forgot were dead ends. Overall, fun game.
