The purpose for a contact page: To make it easy for someone (potential customers) who doesn't know you yet to get in touch.
Sure, “solving” the level isn't that hard, but it is much harder than to click a link. Maybe they don't want to be contacted at all?
Yep. Pressing 'E' for email doesn't even work for me on Chrome. Thought it was neat though.
Very nice idea. A little bit too long for getting in contact.
