Neat twist on the typing game! I think perhaps you should be careful using words from fiction, even if they fit the theming of the game world well. Not everyone knows all of these different words or their "correct" spelling!
Most of the time though it's a fun race to the key, splitting the keyboard in half is a risky but interesting move, I think it works here because each player really only gets to press one key at a time, so you don't run into any ghosting issues.
Good job overall!
