Hey dude, your comments have attracted my attention! I've double checked with my game and also have seen the changes that you have mentioned. However, I've checked the game configs on HTML5 and there has currently been no record of the redesign, only on the Windows 10 App. This probably means that these must be redesign tests and that they'll be released for everyone at a future date. It's also possible that they'll revert the test edits in a bit.
In the meantime, please continue listing what levels appear differently for you in comparison to what you see in the comments section. Thank you very much, and hope you enjoy surfing the wiki!
