Super cool concept! I really enjoyed it, however I think there's either a glitch or I'm just falsely assuming that the 3 keys you get are used to unlock the blog?
I double checked every place but despite entering all 3 in, nothing happens.
Or the second key isn't showing up right? all that happens is Key2: Advertisement.
Below is a screenshot showing what I entered (I checked for accidental spaces and changed the case of letters and words but nothing worked)
