Well what an interesting challenge I set myself for. Basically to do this, when the swarm of Mii’s come towards you on any stage expect Stage 13, hit 4 Mii’s then stop and wait until the final Mii’s show up towards the back of the pack. Then take out all the Mii’s as quick as you can and then you’ll be left with the final boss running towards you.
This is also one of the few times I’ve used a video editor to do a video. For someone like me who are inexperienced of making and editing videos, I rather done a good job if I do say so myself. Unfortunately due to the app I was using to screenshoot this video, 3 watermarks scattered the screen. Why 3 and not 1?? Ridiculous. Hope it doesn’t spoil the footage for everyone watching. Thanks again for your hospitality! :D
