That’s interesting. I’ve only played the Wii version but I don’t recall anybody saying anything was missing at the time. In fact, using the Wiimote to do the paint strokes was hailed as an improvement (having not played the original, I can’t even envisage how doing the strokes with an analogue stick would work)

Not sure how much, but there was stuff missing.

For example the filter that makes everything kinda blurry and dream-like, and a whole ending sequence video with a song, artworks and animations.

Worst part is that video was not removed for a lack of time or anything, but just because it included credits and a logo from studio Clover. You know, the people who made the game to begin with.
