Pokemon rumble u is a fun game to speedrun and not hard either!
Most of the time is mashing buttons or touchscreen.
But because the CPU is not really helpfull sometimes you do alot alone and that can make the game sometimes very lame.
Because the cpu did not help out i died once in the whole run but there is room for improvement later maybe.
The in-game timer show how long you play (excluding the cut scenes including the password screen AND menu screen)
The password i used for gift pokemons are 15137328, 75614557, 68514585 and 94530956.
The whole game is cleared in 1:42:00 (in-game timer)
