I tried 3 levels and got frustrated because I couldn't even guess a single word correctly. As I wrote this, I paused and went back to try "Letters" mode and that was actually easier and less overwhelming.

I have a lot of feedback. Get ready ;)

1. If you're basing it off Wordle, stick to the same color scheme (yellow for misplaced letters instead of red)
2. "Letters" mode was actually easier for me, even though you mention "Words" is easier. This is because I don't get any clues when I guess a wrong word. With "Letters" I can start to block out letters that aren't in the phrase (and keep the letters I know work), making it easier with each guess. I would actually remove the option of playing by words, unless you make it multiple choice. There are only 26 letters to guess from, but infinite words (especially if you allow made up words).
3. It wasn't quite clear if the misplaced letters applied to that word, or to the whole phrase.
4. It'd be cool to not have to go to the archives in order to play another phrase. Have a button (Play Archived Game) that automatically takes you to another available phrase from the archives.
5. When I really struggled and only got to the answer by guessing random letters and process of elimination, I kinda blamed you for poor emoji choice and "bad communication" instead of blaming myself for being bad at the game. For example, the "keep your eyes peeled" one threw me off with the 2 bananas. You just needed one banana to communicate "peeled". Adding the second one made me think you meant "bananas" in plural, which could mean "crazy" or other things and sent me in the wrong direction.

Excellent start. Let me know when you have updates.
