While the narrative was beautifully poignant and the grayscale pixel graphics were uniquely atmospheric, the execution was flawed. The excessive repetition of objectives, the lengthy intervals, and the overall linear nature basically prevent this from being a game at all - simply a story where you occasionally have to push a button to hear the next bit.
I believe this would have been better off as pure narrative - removing what semblance of interactivity there is and reducing the end product to an animation, or even just leaving it as a written story.
If you're going to make a game, you need to go all the way - there has to be some kind of interactivity beyond completing a simple objective to make the player feel needed, if you know what I mean. Even maintaining this format, it would've been possible - multiple conditions that the player could choose between, leading to one of a number of endings, that sort of thing.
It pains me to give this a rating as low as I am because it nearly brought tears to my eyes, but in the end, you need to pick between a film and a game - resting in the space between is playing the jack of all trades but master of none.
