I liked the hide and seek style of this a lot! Took me a while to figure out all of the little nuances and get my head around the layout, which means it took me a lot of deaths! But it was totally worth it in the end!
The Butler himself really is quite an endearing chap too, and persistent. He also manages to pull off being threatening and yet chummy at the same time... I think him calling me friend made it seem like we were just having a bit of a drunken evening in together!
Anywho, it would be interesting to see this concept being expanded on a little, I'm sure there's a story lurking in here somewhere, and I know we're all itching to know more about The Butler's past! Who did he work for previously? Why is he so keen on having a forever companion? Why are we even here? So many questions that could be built on in a bigger story setting!
But I'm rambling now, as is my way. Keep up the great work, would love to see more of this, or anything else you have brewing! =)
