I want to say it's called SHIFT. It's pretty simple, short number of levels but an interesting concept. Black and White platformer, but when you hit the SHIFT key you shift into the other plane, i.e. black to white or white to black.
Been playing that for almost/over 2 years now, I remember first seeing it on the I-mockery Internet board (R.I.P!!!!)
This game showed me 2 of the greatest bands ever, LDoH and Inhume.
The only weakness of the game is Regurgitate.
The Lion King seemed innocent enough, didn't it? But did we really notice all the issues of assault on morality and ethics the first time we watched it? I sure did not. It was not until I sat down with a pragmatic open mind did I even realize the scope of moral violations the 83-minute The Lion King fed our minds.
