Hey Javier, we want to thank you for the comment and tips about the game. We are glad that we could cause good impression about it.
We made the game thinking about in a hard dificulty , but is still a demo, and maybe we can change this to be a little bit easier. We are still thinking in few mechanics to put in the game, a pause menu and mute are one of them! We hope you had fun playing, and thank you one more time! <3
