Es buen.
It's a nice little concept for a game (which I believe is inspired by Frogger, however you're not controlling a frog to reach all the paddles.) and I must admit is a nice idea.
I think it's also a good idea to let the player know how to play the game (even if they don't understand Spanish.)
Overall, it's not just a game, it also includes a nice dosh of education to it...I learnt more Spanish.
Gracias
