The online one isn't has updated or maintained as the downloadable one. You should just download the file above and play the game that way instead of playing the online version. If you're having any problems with the downloadable version then you can bring it up here or in the discord :)
Okay, so yes, your life does depend on it, you just don't know it yet.
Thankfully, some nice guy commented giving a short tutorial on how to download the game for Chromebook and gave a link to the official google doc for the game. I'm gonna paste it below :]
1. download Linux
2. Open the terminal
3. Type in or copy paste this:
/bin/bash -c "$(curl -fsSL https://install.clangen.io/stable/linux-glib2.31.sh)"
And here's the google doc! Google Doc
I could only find one video it was kinda bad, so no video, but hopefully this is enough :]
Also, eventually when it is your birthday, HAPPY BIRTHDAY! :D
Thank you for this! I did run into some problems, however. First of all, downloading Linux is confusing - I wasn't sure how to, so I looked on a browser and none of the versions were free. I did find a free version on Chrome Extensions, though. I downloaded that (It was called Linux Mint, because apparently there are multiple different versions of Linux), but as soon as I got into the extension it didn't feel right, and I wasn't sure how I was supposed to use it.
