Scatterbrained feedback:
I didn't realize that discarding passed a turn.
The rules for placing down multiple words in a single turn is unclear. Unless I'm misinterpreting what the bounties are asking me.
The tutorial doesn't need to be so verbose imo, people can figure out what each shop tab does by themselves.
Look at this SWEET "Yacht"

An in-game word validator would go a long way. I grabbed the letters needed to make "Chibi" but it's not valid.
Also "virality" isn't valid?
What's wrong with "Wax" here?

Show tiles could be toggled by pressing alt or another key. Hotkeys in general would be nice.
If you have an extra tile and discard one tile it wastes your turn since you don't get that extra tile back.
Music is kinda intense for a relaxing scrabble-like game but it's not bad. I like that it gets more intense as you play turns.
I grabbed Wuthering Heights and won by mistake after putting down "Ovum". I say by mistake because I was waiting for my last C to make "knock". Before that I had the usual scramble moment of waiting for the one vowel you need for a bunch of turns only to get two of them in a row (It was a U for "Quiz") but it's nowhere near as painful because you don't have competition blocking the board and stealing your letters.
Yeah, this game is gripping. The tutorial was a bit annoying but it is a more fun and more strategic version of scrabble. Very fun.
