Decent short.
Yeah, I liked what I saw. Simple but effective. Being that simple, there's not much I could say about it, but it worked well overall. I think the music could've been a tad quieter, but it helped keep my attention and really suited the pace. If there was no audio, I probably wouldn't have finished watching your short.
Perhaps next time you could release several shorts in one submission using this basic style? Keep experimenting.
