Good work! The theme fits very well as the father/Guy/whoeverknocks is too late :D I did not get the ending though... I laughed when hearing the "music" nice idea on using this mumbling for a soundtrack :D Still: Would have been nice if there is more music or SFX eventually. The art style is simple and enough for presenting story, also some more variations of certain things or consistency in the style would have been nice. It's a nice idea trying to combine the pixel art with real images, but does not work all the time...do you know what I mean?
Still: Good job!
