Good animation, ok story, great trilogy
I must say, your first "2 min terror" were good, your second one was great (Really liked the second one, pig mask guy was awesome), but this was not as scary as the others, don't get me wrong it was good, but I think you could have been more original with the monster, like you were with the previous ones.
When I saw the tarp get up, I was expecting something like a messed up ghost creature that could probably live in Silent Hill like your last one . But it was a flesh eating plant, don't get me wrong though that plant was still awesome. It's just I think I saw man-eating plants and haunted houses in horror movies before.
Other than that, everything else seemed great, the pit fall startled me, made me jump out of my seat, the animation was also pretty good too, the backgrounds to the videos were cool, and the audio was good too. 8/10 keep up the good work
PS. Sorry that this is so long
