In order to get past the eletrotiles at the beginning you just have to watch them and cross over at precise moments. It's a matter of timing and luck. Electro tiles can be a pain but once you get the hang of the timing you can make it. Just have patience.
Like I said the search is also helpful. If your search for 'w10 l10' doesn't help you try also searching for 'one last hurrah'. Good luck
