Now I'm not a (total) idiot, obviously I can debug it if i have to (and if other people are telling me "there's stuff there, you just can't see it").
If i open it in chrome with extensions turned off or a default mobile browser, stuff now appears, so yeah, its got to do with script permissions and the like.
But again, why not just include actual text in the "what is google ctf" section that answers "what is google ctf?", and/or in the beginner's section that explains what's going on, and of all the groups of people you'd build your webpage for, are security people the ones that you want a website that breaks if they block your default scripts/permissions?
Every puzzle here places you in a different unfamiliar situation. The only "outright disqualifying" thing is whether you can figure out something on your own. You essentially failed the first test.
