One of my favourite things about Glitch starting up was the stuff I could do from my browser/mobile, like character customization and skill-choosing. I still think the Glitch API is one of the most well-utilised that I've seen, but that's a story for another time.
I think it would be great if there were an option to do Upgrade Card shopping (same as ingame, three visible until you buy one/reshuffle) via the browser (does AJAX do that? I think I'm thinking too technically here). Anyway, yeah! I can't be the only person who wants to reshuffle and see what they get at 3am without getting out of bed to check my laptop. Right? I'm not the only one who does that? D:
