### 5/5 — Can’t buy full game on iPhone

*2023-03-19*

I have this game on my desktop, and I wanted to get the full game on mobile. However, it does not allow me to purchase the full game.

### 5/5 — Love the game but it’s clunky

*2022-10-03*

This game is super fun and addicting, but the controls are really clunky. I have accidentally made palindromes and clicked on singular squares so many times. The note taking feature helps but I feel like it could be improved. Maybe make a button you press to confirm each move. Also the user interface is super ugly and hard to navigate. Great game, bad controls and UI. Can’t wait until this is updated because otherwise this game is 5 stars
