Shit, i'm gonna have to disappoint you, this is not a master mode update, unfortunately. In my defense (:D), i did mention this in in the roadmap. V2.0.0-a3 will revamp the master mode, and i have a lotta improvements and new features planned for that one. Master mode is my favorite, i basically created it for myself because there aren't many games like this out there.
Sorry for disappointing you. However, i can promise you that v2.0.0-a3 is gonna be awesome and unique when it's out.
