The atmosphere is pretty chill, but it was pretty difficult to understand that a giant dynamite stick is a portal, lol. I've also found your easter egg! Although not sure if I can help much with that. You should also reload scene during every restart, because parts of game are becoming inaccessible otherwise; for example, I've kicked portal into the sea before interacting with it. Also trying to kick chest into the sea might catapult you way outside the drown collider, making you fall infinitely into the void (I still drowned the chest btw, lol).
