Menu is in chinese, but isn't too hard to navigate through:

title screen
1st button - nothing
2nd button - start game
3rd button - change keys

in case you want to change keys, here's what it says in chinese

up
down
left
right
fire
jump
grenade

when you start the game, there's 3 more buttons to choose from, that's the level of difficulty.
