Nice clean graphics that suits the game. I feel like this would make a pretty nice mobile game to kill time!
Though I have the same opinion as one of the commenter below that it's little bit annoying to have to click on the block to type in the text. I feel like having the music be pure instrumental is better, as the vocals are kind of distracting me from my monkey brain to think up of words. The color is also a bit weird in that, sometimes the letters that are completely wrong is highlighted in orange instead of red. If I saw orange I would've thought that maybe the letter is correct but it's in the wrong order instead of not being completely used in the word.
Another thing to add is that maybe a further hint can be used like hangman, where it gives you some of the letters.
As for the reversal part, I struggle to see the reversal part. I feel like it's pretty straightforward to guess the word through the hint. I wonder what does the yellow button do, it doesn't seem to work.
Overall, a nice chill word game!
