Hello there, fellow gnome enjoyer lol.
This is such a cool idea. Making typing the whole control scheme (even on the title screen) is genius, and it instantly teaches you how the game works without needing a tutorial. I also really liked how you can select/switch gnomes purely with the keyboard; really cool design choice.
The command variety is fun, and once things speed up, it gets that chaotic feeling where you're frantically typing and routing everyone to safety. Really memorable entry, I could totally see this concept being expanded into a full game.
