Nice particle effect for the scream! Overall nice execution in line with the given theme. Simple and straightforward, but not bland at all. I did find that I was really pressing only two buttons the whole time though: D + scream. For me the particle effect eventually became too much (my brains are easily triggered by repeating patterns or flashing lights) so I couldn't continue playing for long. Maybe some kind of low-contrast option would make wonders, and I'd love to see point system or some other way to know how you are progressing :)
