Da Pink Knight GUIDE-(Also, disappointing ending scene)-
The challenge added a lot to the overall composition, it was pretty damn possible but still took strategy, technique and practice... Still, I was really disappointed by the ending 'movie' which was executed in a sloppy way that really isn't worth all that battle.
Anyway, hints:
At level one- Don't try to hit him straight on, keep walking towards him and going down too. That way he'll miss his punch and you can go on and get 3 ground strikes or about 5 aerial ones if you can jump while walking. Repeat until you level.
At level two- Stand back and reflect the cannonballs, don't hold the button though as it will only make the bomb fly away instead of hitting the bot. Once you've reflected three of them right on his face it will be stunned, take that chance to beat the hell out of it, I strongly suggest aerial attacks.
-Note: You might skip to level 4 if you execute it correctly
At level three- Now he's got a strong, double, ranged attack. Yeah, you're pretty screwed... or not. Since you reached level two you acquired the ability to run, so repeat the process used on leve 1 while running, jump when you get close and aerial his metallic wooden head, try to fall close to his feet. Once you land check this: are you right over his feet or a little more far away? If you landed correctly, you can jump back to his face and pawn him again, otherwise quickly do a single jump away from him (you'll dodge a punch and still have time to jump again if he uses his saw attack).
Level 4- His new attack barely does anything, seriously. It's horribly easy to dodge and counter. When he starts to spin, walk to the bottom of the screen. Make sure that he won't hit you there on the first walk. Once he hits the invisible wall right in front of you, run towards it while it walks in the other direction, turn back and fill it with dayli... pink hearts.
Level 5(1)- Now he'll summon tiny knights, simply ignore them and repeat what you've learned for levels 4 and 5. ( you can kill the knights with magic when he spins if you wish)
Well, after you finish level 5(1) its armor will open. Rapidly beat that ugly pilot like there's no tomorrow, remember that you CAN'T reach it with ground attacks. Once it closes up again you'll delevel a bit, act according to the level you became.
Once you level to 5 again you might go to 5(1), but if you really hit it hard you'll go to 5(2).
Level 5(2)- Now it summons knights and shoots spiky things, which turn into weird blob creatures. Don't let the spikes hit you! Try to deflect them if you can, once they hit the floor they can't be killed and will turn into blobs. Avoid blobs and knights, deflect spikes (or dodge ifyou can) and repeat 5(1).
You might have to repeat level 5 a few times, but once you're done... you'll be done :D
I'm rounding it up to 5 stars~
