That's about the size of it, and I might have posted this before, but chip cheezum has a really good LP of W101.
He explains all the game mechanics, shows most of the secrets, and gets platinum on basically every level.
It's worth playing through blind, then watching his LP of the first couple levels to explain what's going on.
Like how the X button also works as lock on, can shoot out AI controlled unite morphs, and how unite guts/spring are the dedicated dodge/block moves.
None of which are explained except for assist morphs which was a 2 second tooltip I skipped through accidentally in the first level.
