Why are only 12 buttons usable, and not 16? Is that how it was on the old Nokia 3310? Couldn't the games utilize the C, select and arrow keys on top?
(Not that I plan to use 16 buttons necessarily, mostly curious.)
This was a rule carried over from last year and if I remember the controls for space impact and snake I found only used the keypad. The four buttons (C, select and arrow keys) were more for menu navigation/things outside the game. Ill look into it and update the rules for next year if I discover anything else.
