Creator of Minecraft (5)
I believe the answer is:
notch
'creator of minecraft' is the definition.
(I know that Notch notable work Minecraft)
This is all the clue.
(Other definitions for notch that I've seen before include "Indentation - step up" , "Gouge" , "Incision; indentation" , "Snick" , "Tallying incision" .)
