That happened to me this morning. After all the talk of 2.0, there was an update, but not geometry dash xD
No, he's probably working on the final and complete changelog (that actually tells us Level 19's name) for when it releases on the App Store and Google Play.
It would still be flat but the portal would make it look vertical. Kind of like the backwards portal. It's still forward but it looks backwards. And besides. A vertical portal wouldn't for the screen
According to http://www.appreviewtimes.com it says that the average wait for apps to be finished reviewing is about 6 days. Lets hope it sneaks out before that
Last night Ihad a 2.0 dream where I found out apart from Level 19 and Deadlocked, there were two more official levels using new blocks we've never even seen. All of the early official levels were redecorated and it was a thing between famous creators to remake their famous levels with 2.0 elements. I remember "DeCode 2.0".
I think there should be an achievement called artist, you unlock it when you have 5 featured levels. it gives you the ability to make your own icon.
