Tried buying early access through the humble widget, but the thing froze during processing and there doesn't seem to be any download option on your website.
I still received the automated email from Amazon that payment processed successfully but it doesn't give any download link either. I've never used Humble before so I don't know what to expect, but if there's some sort of browser support issue then I don't appreciate the lack of warning/guidance BEFORE trying to make a purchase.
Disappointed that I'll have to wait who knows how long for some customer service person to resolve the issue, and I am never going to make a purchase through Humble again.
