A koan is a question that beckons you transcend your preconceptions of reality and it's laws.
Considering the game's premise, I deem room exploration a time wasting design error. As for the puzzle on offer, the question and answer are linked, but arriving at the solution is an arbitrary process, mainly because of the lack of interaction with the solution's elements.
The game starts with a great idea that, in irony of it's zen roots, can only bloom under a more focused design.
