; (routine needs to decrease bombs because it's called at the end of each level
|
||||||
|
; to give you a bonus for each bomb left, so instead we patch one caller but
|
||||||
|
; not the other so you can plant a bomb without using up a bomb then get the
|
||||||
|
; maximum 'unused bombs' bonus and advance to the next level)
