Yeah it is true. Everybody is trying the arrow keys hahahaha. At the beggining I wanted to create a comment for EVERY key on the keyboard. But you know, the deadline came so fast. I am also spanish, so I have to translate it with a friend. Anyway I glad to hear that you enjoyed it. After the voting I will release a version with more comments and an in game tutorial about throwing the wave bombs, something that a lot of people is missing.
