There's so many more brutally hard games you could easily do a part 2! Ninja Gaiden, Enter the Gungeon, Celeste, Hollow Knight, Crash Bandicoot 4, Super Mario The Lost Levels, Ikaruga, Returnal, Contra... the list goes on!
Very surprised that celeste wasn't on the list. Fantastic game that will absolutely kick your butt especially with the C-sides, final chapter and getting the golden strawberries
