I agree with Scoot-o-Speed that the 4th wall breaks were very strong. I was expecting those to pay off in a game-mechanic sort of way from how they were being used.
I noticed I could walk around the pier from the sand and tried to get out of the labyrinth that way, turns out I couldn't, haha. I'm sure this is more of a jam limitation, but it'd've been nice if the beach by the pier didn't let you walk down there.
I loved how the left-hand rule (as soon as it was introduced by that crab) got you directly out the way you came in, and if you followed it from the entrance, took you straight through. Great touch. Naturally, I didn't try this until I wandered through the labyrinth aimlessly for a while.
Really enjoyed Gavi's skipping animation, though Gavi's hitbox often got me stuck in dead-ends in the maze.
This was probably also a jam limitation, but the repeated crab dialogues had me doubting my sanity. (I just went back in to confirm there were repeats, I know at least the "Day 430: running out of supplies and missing my family" and the left-hand rule repeats). I was expecting to be able to use what crabs said to me as a metric for if I'd talked to a crab before, with the meta-expectation that previous visitors wouldn't speak to crabs word-for-word even if they talked to the same ones a couple of times.
Very cute! I don't trust Owen at all, Gavi seemed trustworthy though!
