Im gonna try it now, you will get feedback later.
Ok i tried it, and i had an awesome time playing it
But i think some rooms are way to big, try to reduce the size of them in the your next CS.
Also, your custom story only scared me once because it was way too expectable.
the only time i jumped was when the closet opened by itself and i got killed by the brute hehe.
(sorry for my horrible english) it's pretty late here.
but DUDE! you did a very good job.
i hope to see the full release
i rate this map 4/5
