The no menus concept is great and executed with confidence. I typed "play" and the game started. Making the entire interface the game's own verb is an elegant idea.
The look is clean and pleasant, light beige background with coloured letters (purple, blue, orange, green) with little white shadows and dashes under each letter marking the positions. It reads like nice teaching material. The HUD is minimal and clear, score in a green square on the left and a circular red timer counting down on the right. The end screen showing the word that beat you ("Failed with: savvy") plus what you actually typed is direct, useful feedback. And unlocking new words by beating records is a good way to give it legs.
Important caveat: my result here isn't worth much. Because of how I play, the game registered every one of my letters duplicated, so "savvy" came out as "avvvvvvvyyy" and I finished on 0. That's a limitation on my side, not a bug in your game, and anyone playing with actual hands will be fine.
What I can fairly comment on: the 2 second timer on the first word is short for someone who has just understood the rule, so three or four looser opening words would make a better warm up. And since it's a 100% keyboard game, it's worth saying on the title screen what to type ("type PLAY to start"). I only knew because I'd read your itch page, and I guessed at "play" on luck.
Strong idea and clean presentation. This is one to play with your own hands.
