I really liked the concept of this game: a word game mixed with a physics game, my two favorite genres of mobile game. But what I got was simply a physics game. A word game, typically, rewards you for knowing lots of words and what they mean. It at least encourages you to learn new ones. Any game where “llllllll” can be the answer is not a word game. It is a game that uses *letters* in a new and creative way, and props for that. But it could be so much more.
What I would do: with each puzzle, include a definition or some cross-word like word hint that leads to a word which will satisfy the physics puzzle. That way if you get stumped on the physics, you can focus on the word hint, or vice versa. I downloaded this game at midnight, played it for 20 minutes, and then deleted it the next morning, because the charm and novel concept had worn off. The game that I’m describing, I would play for hours, and the game you’ve got is not far off. I just think it’s borderline false advertising to market this as a “word game.”’
