I can't watch the above clip at work, nor can I follow any links through it, as my work blocks out this website.
Tell me if it's any good and if you can find a link to the website, give me a link too, please. :D

its pretty funny. It's basically recreating the 2-d platformer by making it a narrow 3-d corridor and having headcrab zombies coming at you as the baddies. The environment looks like the original castlevania, right down to the low res pixels. Pretty funny, not sure if it would hold my interest for more than 10 minutes
