With the release of Crush 3D Planet3DS.de compared the two games unveiling the totally different style of the same game. While the PSP version is dark, rainy and has a touch of depression the Nintendo 3DS version is cheerful and happy.
A general attitude of the two companies, a choice specially made by Sega. What is your opinion about this topic!

EG:Crush is a palate cleanser in the best possible sense, then: it's light, smooth and leaves a very pleasant aftertaste. And unlike its candy-flavoured namesake, there's not a whiff of cynicism about it.

CRUSH is a simplistic puzzle game from Radiangames which is actually challenging. Read GameWoof's review of CRUSH, a well-polished Android game that's worth the download and the measly price tag ($0.99).

Don't let the simplicity fool you, the challenge and beauty of CRUSH! delivers.
It is insane how much the changed the stile of the game for the systems. But if it isn't postapocalypic and dark no Sonyfanboy would play it and the Nintendo customers would be scared of the old style :D
I kinda like the style of the PSP better, eventhough the graphics of the 3DS look crisper. Don't like the candyland-style...
I agree with Sorano here. The style of the PSP version is far more intriguing than that of the 3DS version. However, everyone should really play this brilliant puzzle game - be it on 3DS or PSP.
ima be honest with that kiddy artstyle and kiddy chars theres no reason for the game to be dark
