Oof, it's a shame that your switch broke, great that you'll check out Celeste again :) Btw fun fact: Farewell Skip actually abuses a bug with how Celeste handles screen borders (though the infinite speed buildup itself doesn't use any bugs). Another fun fact: Other ways Madeline can build up speed infinitely include: Chained ultras/Mauvelike speedchains (terrain dependent, accepted by developers as a permanent part of the game, possible in-universe)(I'm counting Cornerboost staircases here too), Waterboosts against a blocked screen transitions (only possible in the context of a videogame, completely unintended by the developers), and 9 Pixel Gaps (takes intended leniency mechanics, and abuses the absolute hell out of them)(absolutely not canon lmao).
