You should really change the viewport dimensions for your game here:
That's an easy fix.
I had to manually adjust it in the webpage source using inspect to even play
There are some bugs I found: Going in the house soft locked me, I could only see a corner of something and nothing else. Opening the menus in the opening sequence makes it so you cant pick anything up. I had a duplication glitch where a piece of driftwood stayed behind, giving me infinite wood.
I like the opening sequence there, very Firewatch, and the guy is super cute if a bit crude. I could be missing something but there wasn't much in the way of gameplay but the core idea could be interesting: Deus Ex style inventory meets a retail type game or whatever you call it. There's a lot puzzle like opportunity in that space. Like different stages: collection, shipping, selling, packaging, ect. with different shapes and sizes could bare some interesting emergence. Keep going and mine the space for interesting interactions, there's gotta be loads!
btw I totally relate to the over scoping; I massively underestimated my project
