This is definitely a good improvement over the original. Parts of it make me feel like I am running around in a castle whipping vampires. Which is not actually a bad thing in this case.

The last two minutes or so could probably make a fine track just by themselves.

Thanks! :) I tried to make it sort of dark without making it sound scary and.. strange. Glad that worked out somewhat well. :)

Yeah, but a two minute song is pretty short. x3

I think it's just a personal philosophy of mine. I am a big fan of electronic music but even the bigshots sometimes get lost in looping things too much (Daft Punk's Robot Rock is like this, but intentionally so). In this case it still seems to work out well, partially because you mix up the tone and pace so much as the track progresses.

I definitely got the same vibe that you are describing... A kind of friendly darkness, I guess you accomplished your mission.

One thing I always try to keep in mind is to not make things repetitive and boring - which can be pretty hard to actually hear when you're writing the music (at least for me). But what was really interesting to try out, was to actually use only 6-7 different pieces/loops (that I also make myself, I hate using premade loops :P) and try and keep that original by, like you said, mixing the melodies, bass lines and beats up.
