I like the idea and the gameplay.
It would be great if you added tutorial or a simple "How to play" page somewhere. I had to go back to the store to read the rules. Also there's no way one can switch the sounds off inside the game. Adding some reward animations when user solves the word and maybe some levels progress will make the game more interesting, as for me.
What I like:
- the game has many different modes
- skins store makes it more interesting to gain coins
What I dislike:
- it's really very difficult from the very beginning. May be it could be better if difficulty progressed slower
-once you select a letter there's no way you can remove it. It's especially annoying when playing 3 strikes mode
