Finished the demo for both 3DS and PS3 version. The 3DS version is especially terrible: long boring unskippable intro; slow, simplistic gameplay that has tons of interrupting moments where you have to take out the stylus and fill/erase out a shape on the touch screen to make a platform or barrier on the top screen appear/disappear. Slight variation of this occurs every couple seconds of walking forward.
The PS3 version feels like it's a port of the first game. The camera, when using the dual analog controls, is slightly better, but overall it still sucks. Camera stuttering still occurs, and many times the context sensitve button inputs does not register.
