What would make this game neat, is maybe a little transition to color as you get further from start. Like an "Escaping into the countryside" thing. Or something...
Oh and it isn't illegal for the games to look similar. The gameplay is similar, but in this, if you actually played it, is partly about discovering new species, and has no "Eat red cell to go down a level, blue cell to go up" That's like saying the new Medal of Honor should be illegal because it is like Call of Duty 4. Besides, fl0w is a free game, for computer at least.
fl0w was not made by SONY. Just sayin. It was made by Jenova Chen for computer, then SONY made a deal with him for him to make 3 games for them. Jenova Chen has some amazing games though, the only one that hasn't been on PS3 was Cloud which is really neat. USE GOOGLE PEOPLE!
