I enjoyed the game more than I thought I would when I stated to play. It was such a relief to see the guards pass you by.
I like how you mixed puzzle, exploration and luck. And the way you forced player not to turn back by a ball and chain that also prevents guards from chasing you is brilliant and I've never seen something like it before.
Unfortunately I couldn't find the 5'th key of the set of five doors as I needed a lot of luck to search properly. (And I managed to pick 9 bones)
Great entry as you were also working on another submission. Well done :)
