The game is very nice and has a system that makes it somewhat interactive and attractive to play, the most serious problem that I see is that with 2 minutes of play you are not penalized for making mistakes, you make as many mistakes as you want, you can spend the level in a matter of seconds. It does not explain in a concrete way why one letter is lower or higher than another, it just tells you that it's just like that and that's it. Taking that aside, the game has many possibilites.
