I never played Doki Doki Literature Club Plus so I’m not sure what has changed. So comparing the original release of DDLC to Miside, they are similar as you are pulled into the game and dealing with a yandere type character that requires you to mess with files/game versions to progress through the game. Miside doesn’t need you to do anything to your save or game files to get the endings and everything is done within the game itself while DDLC required you to go within the games files on your PC to progress further and I believe even reinstall the game for one part.
