Definitely one of the better-looking games I've seen here, or in any game jam in general. The lore is also really interesting and fleshed out! As someone already mentioned, the performance is a bit of an issue, and a simple patchwork solution you could try implementing in the future is just adding the option to download the game, as that can often fix any lag caused by the player's browser. You definitely have something special here though, do carry on whenever you have the time!
