1) Thank you!

2) Ah that's really stupid of me, `.stream` was our staging server. I should mention this somewhere, codesandbox.io should have the latest version with live.

3) Good one! I'll update it.

4) That's a super nice sandbox, I love tutorials that use gameplay, makes it much more fun to learn. I'd move it to the io domain, because our stream database is horribly outdated. I'll add a redirect from stream soon to avoid confusion.
