I knew it.
I knew I'd played this some where else before, Hyperframe I guess it was called? It's like the same exact game, graphic of the cube and levels. It doesn't matter if "hyperframe is not popular", it was still taken from hyperframe. And that's wrong if you didn't get the original creator's permission.
But, besides that, I like this game. It's fun and a bit challenging and a great way to pass time. I'm not going to give the game itself a low score just because it was taken from somewhere else.
