Spacey but not boring
This game has it all the pefect graphics the sounds you hear when you froze a ball or reverse time i wrote all the good and the bad thing of this game on a note and the only bad was that time reverse was a complete reverse (i rubbed it out because it would be way to easy then) and the story of a particle accelarator i also enjoyed portal but it seems to be this game is almost a an equivalent when you compare the innovative ideas it is an game to be proud on !
