Do you mean Beyond Heaven and Hell 1.2 by Piramuat? Because that's a cool level too. Also, there's a Beyond Heaven and Hell (followed by Japanese symbols) by Vihdarr that's awesome. I suggest playing both.
I also recommend Dinosaures Island by Feistyfrog, and The Final Frontier by Super_Sonic5411.
Also, The Underworld by Hyams is the bestest level ever.
