Question about deco'd DS cases

[princesspikeru.livejournal.com]

This isn't really a lolita question, but I'm hoping it will be allowed in the spirit of the monthly theme? *fingers crossed*

Does having your DS encrusted in cream and candies ect make it awkward to play games that require the screen being turned to the side?
Seeing all these awesome cases makes me want to get one, but not if it means taking it off every time I want to play Rhythm Paraside, especially since from my experience that's when cases break.
