I'm just going to admit that at 13 I definitely would not be able to create something like that, so kudos to you. I love the concept, that your character can only move left and you have to use other methods, like the push buttons and platforms, to move right. The escape sequence was nice, I liked your use of the particle system. I have two suggestions for you. The first is to go crazy with the player's icon. You don't need the shape of a person on it for the player to recognize it's the piece they should move, you could add eyes and a mouth or something like that. As a time cube, I think green would be a cool color. Also, maybe add a bit more challenges beyond the button and the push platform. Beyond that, however, you have an amazing game on your hands!
