Celeste has an assist mode, which uh I simply did not use Idk. I tortured myself with its twitch platforming and felt I overcame it, but I don't even think assist players are losing out on much.
One of the other things Gamers™ need to accept is that the designer's word is not necessarily law. As far back as the Game Genie, people will use whatever they can to experience a game and that's fine honestly. People also want different things from games. It's like the author is dead.
Just FYI, the "author is dead" thing is about interpreting a text directly according to what is actually there, without concerning yourself with what the "Author" may or may not have intended. When you talk about altering a text, by example, modding it or using a Game Genie, this is actually something quite different, because you are actually creating a new text that would then require different interpretations from the reader
I selected the Game Genie because it's not capable of adding stuff and it takes a lot more codework than normos would do to change the game considerably. But U Rite, modding especially is more like fanfiction, analagously.
Video games are actually interesting wrt the conception of authorship, because it's even harder to assign a unitary Author to them. Hundreds of people have input on the finished product. Thousands if you count people like QA and beta testers.
A lot of games are also based on long community traditions of modification too. Popular games like League of Legends and Dota2 for instance are based on a mod called Dota Allstars which is itself an amalgamation of other popular Warcraft 3 mods along with solicited direct incorporation of player suggestions then of course the base game of warcraft itself is a rip off of warhammer and it goes on. The ability to modify these games is often an encouraged and developer supported core feature of the games.
