First things first: for a speedIF this game is astonishingly rich. There are only two locations, but many items that are implemented, some of them with nice descriptions. The story concept is also nice and motivates the player. Also good: after a while it is clearly stated what has to be achieved to win the game.
But then it becomes incredibly hard to deal with the different objects; I had to take a long look at the walkthrough. It is almost impossible to find the solution: exact timing is necessary to make progress, and if the right moment is missed, the game can easily be brought into an unwinnable state without any information about it. There are hardly any hints given which object has to be used at which time. Some aspects can only be found by guessing them. The difficulty level is increased dramatically.
So, playing this without a walkthrough is almost a waste of time in my view; it is a pity that the author has not revised this game with an otherwise fine premise and added more hints to make it more accessible.
