Hey there! Loved playing your game, reminded me a lot of HP Lovecrafts "Shadow over Innsmouth"!
You managed to make this a intense experience even in daylight, the whole atmosphere is getting across very well!
There was just one thing for me - i felt like the ending was very abrupt. With the song of the sea crafted and upon finally getting to the water facility, i was keen to see the inside of it and finally discover the backstory to the whole thing, as well as reuniting with grandfather. I feel like it ended very quickly there, which was kinda sad.
But - still a dope game. Thanks for creating it!
