Superb game. Nice puzzles with thoughtful solutions that required revisiting islands. Reminds me of Monkey Island without the puns. A few places where the clues required a lot of guesswork, but felt they were fair in retrospect. The tree cutting puzzle was probably the hardest. My guess is the game might be harder for non-native English speakers?
Fun fact: species in the True Firefly family (Lampyridae) are called lampyrids, though other insect families also contain "glowworms" (bioluminescent larvae)
