I like the gamification of the old "Boss Key" into a game itself, nice idea.
The "typing"-game was nice, although i felt like somethings inputs for the ultimate were lost but this could also be a skill issue on my behalf.
Two things I noticed were unclear to me when i played through blind (I love to always skip the tutorial), but since these things were explained in the tutorial its fine.
Love to see some more polish over the GUI.
