I think it was because I was playing the game through https://itch.io/randomizer?jam_id=385666 instead of on your page directly, probably something to do with the incorrect COOP and COEP headers. It works when I go to your page directly, sorry for the false alarm!
As for my review, I really really liked the art style! The GBC theme is super clean, and the sprites and backgrounds fit the aesthetic so nicely. The title screen was super nostalgic, especially with the chiptune music. Great work on the presentation!
The gameplay definitely leaves something to be desired unfortunately. The fishing took quite a while, especially with sometimes needing to fish multiple times before winning the next fight. The fights were also sometimes a bit long as well.
The story was simple but the unexpected ending was quite a nice touch and interpretation on the theme.
