I love the concept, but the presentation is mid. First, the character we controlling isn't very different to other "ghost cube". Second, character that we controlling is spawn randomly, sometime very far from map, sometime right next to the "Win Door". All two of that combine in has create a mess of chaos.
Ex: Don't know where and which cube are the character that we controlling, Randomly win the level because of spawn next to "Win Door", ...
But after all, It still good to play, Keep improving.
