Heh, yeahhhhhhhhh the game is a bit big. Honestly thought I was done with optimization, but I didn't realize this game is like 4 to 5x bigger than a standard indie web game. I knew it was big, but I didn't realize it was THAT big in comparison until I looked into the standard size for web games right now. I'll see what else I can cut out/optimize, thank you for the feedback!
Edit: For anyone else reading this, the game has been heavily optimized since! it is now around 80 mb! (the download is much more because it uses high resolution images)
