The contra one is soo annoying ive done it 3 times by now and had 30 seconds to spear with just contra to do which ive been trying do so all the way through anyway. I try it with caps, without, shift, caps and shift as all the differant ele colours i tried everything and it wouldn't work!
i lost my man on the level just after you get the pink guy it wont let me leave without him if hes not with me so i kept bouncing off the door but then i fell in but still stuck in that screen
wayy to hard had all upgrades at lvl 6 and still was very hard to do last weapon is useless for what its made out to be now the boss is impossible i cant keep dodging his bullets
might aswell do it blind i have a fast computer and set quality to low but it still freezes and when the image moves again your dead unless i manage to jump them
