I had the impression of playing the conclusion of a story I'll never know. As I play the character, I ask myself: Who am I? Why am I depressed? What led me to this cycle? Clearly, the game isn't made to be won, fate meets end, I never seek help; it seems I am too helpless for that. But that's about it, no significant character development to avoid saying none. As I said, the state of the story looks like you just wrote the end and omitted the rest. This leaves me with the cruel feeling of not caring for the character, may he die, I've only played the end of his part, I have no way to truly appreciate who he is.
As for the world itself, I see a theme here. Where every pixel is grey and large, the chunks of the world are abnormal and separated akin to a fantasy skyland, with sci-fi teleporters here and there. Happiness leads to death, avoiding it is meeting victory conditions. Opening your heart to more displeasing thoughts and somehow being fine with that. I conclude the character may experience extremely blank, repetitive, sad and confusing world, however he seems as blind to help as he is colourblind and I would be depressive too if I had to hear this song everyday; I can understand why the only vegetation is what appears to be grass.
The game itself is exactly what the character of the game feels; sadly repetitive and we have to cope with it to see the end, which is, you may have heard of it enough by now, unsatisfying. Overall, the game isn't too terrible, but it could improve graphic wise, story wise and animation wise. Your mini games are over used and unflavoured enough that I don't see how it could be fixed.
