Only thing I would have suggested to add or to change (If a similar genre of game is being done!) is to add something else to be done in between the fishing, other than rowing away from the Tree Huggers. Maybe the player fishes out some notes or journal entries and that tells a story or goes deeper into the lore and setting, that would have been more enthralling rather than just doing the same fishing task over and over for an hour. Though I still found the gameplay look to be very fun and relaxing (And spoopy >.>)
Also maybe changing the environment the closer the player gets to the end goal would also maybe have been more scary and would show that something is coming or something will go wrong.
Overall though, I really enjoyed this game and it was very fun! Intrigued as to whether there is a sort of Eldritch horror universe you are creating with Don't Watch The Moon and this game, excited to see more! Good luck for future projects!
