Unfortunately, adding your own fonts would be impossible by definition, but creating your own custom themes is something that's definitely coming down the line! ^^
It could also be that Vercel automatically blocks certain IPs for whatever reason. Even had that happen to me a couple times, and as far as I'm aware, I don't seem to be living in Iran, Russia or China lol
noooo, I can't let that happen! if you want, you can privately message me on discord or email me with your browser, OS and all other relevant info so we can fix it ASAP (it might be just Vercel's anti-bot mode though)
Don't worry, not in this case! Generally speaking, cookies first collect data on the client and then send it over to the server. But in our case, there is no server (backend) - it's just a client-side Next.js application sent over to the client (your browser), and the local storage that stores progress and preferences data in the app just lives locally and never actually leaves the browser! We (well, me) have no idea what progress data our users have, because nothing is sent over from the app (you can see for yourself by checking your browser's Network tab!)
