Very hectic gameplay. It took quite a bit of experimenting to understand that I was supposed to slide through the words like in fruit ninja. Once I am used to the core gameplay loop it feels quite satisfying.
Like others have said this game is extremely difficult due to the infrequent appearance of useful words and how your opponent can steal words that is not on the screen. I feel like it would be better if he was actually competing to find words on screen so that would at least give you a chance of beating him in time. I finally managed to beat him but that's mostly by abusing multiple # tiles to pretty much force a long word. The bombs are quite a hassle too and it might be better to have more frequent bombs that only explodes if you accidentally cuts them like in fruit ninja.
That said, the game is very well polished. The UI is slick and graphics are clear to read. Great work on the submission!
