You wouldn't be wrong. I have read Worm and enjoyed it, although it was actually recommended to me after Super-Nova began.
Interludes and some other elements of the VN like the post-bad end "advice room" were more inspired by Fate/Stay Night, but either way, I've absorbed influences from a number of different superhero stories, including Worm (I haven't gotten around to Ward though).
The basic premise and a couple other minor plot points, for example, were inspired by Dreadnought by April Daniels - a pretty neat superhero novel with a trans lead!
