Good work, great meaning.
Just a hint: to make it more enjoyable you should make available the first four items at the start, so the "player" can choose the order, and when all the tools have been used make the last tool available to break the wall.
Even if it is not a game, let the user choice which tool use first make it more entertaining and the users will stay till the end without find it "guided too much".
Thank you for this work :)
