Very tricky to start with, but I see how it can grow.
Mapping arrow up to "MOVE UP" instead of "LAST" (and arrow down to "MOVE DOWN") makes it just a bit user friendly to beginners, but much less for your target audience (it's quite annoying to type "LAST" knowing the alternatives). And the UI is non-intuitive, there probably is a bug showing a "TOOL" before you ever crafted and equipped it (I only got that after eqiping a pickaxe).
I would recommend you to ditch the normies and completely remove all the UI/controls, or to fully make a normie UI and ditch the console.
