Yes, i would argue that the music and art direction are sub-par, by most standards. A better argument would be to say the lack of those elements are due to the small development team and the budget for a particular "game" like this.
Well I can't argue with "reasoning" like this.
Why, because I understand why people would buy these indie-type "games" in the first place?
No, because you don't seem to understand that music, art, and graphics that you don't personally like doesn't mean that it's extremely sub-par.
Again, no need to explain why you like it
You seemed to be explaining why people want it, which was wrong, and I told you.
Compared to what exactly?
Why does it have to be compared, exactly? I think the graphics are incredible because of the great pixel art, design, use of colors, and quirkiness.
I rarely use the 3D function on the 3DS as it doesn't really enhance the experience for me and just eats more battery. The cost/benefit ratio doesn't seem worth it.
I mean 3D graphics. And this assumption was from the fact that you call Sound Shapes, Lumines, Tetris, etc. "non-games" while Skyrim is in a whole other league.
