asking for improvements/suggestions on current project

[bttf]

yesterday i made a small demo consisting of sprites with an accompanying sound-bite that plays when the sprite is touched. the player is also able to navigate through sprites.

binary: http://gethightothis.com/bttf/petsounds.nds
source: http://gethightothis.com/bttf/petsounds.zip (including .wav files)

please enjoy and let me know any comments, criticisms or suggestions concerning the demo or the code. i am posting this on here because it is a learning project for me and if anyone can provide a little bit of insight on how to make it better i would gladly appreciate it.

thanks
