You have a greyhound you need to protect from incoming missiles. You can BUILD a wall, which will stop missiles, or you can SHOOT them, which will pierce missiles. press X to switch modes if your wallometer > 4, you cannot start building if your wallometer > 7, it will stop building you can have 4 missiles on screen at once. game made entirely by me in one night except for library assets (not missiles) and the explosion effect music by rtest1x (thank you)
