Not a bad spot the difference type game. I think there's some differences that are way too subtle and I wouldn't have spotted them if I didn't cheat. One thing that was missing was some sort of counter that showed how many portals you had left since I didn't know how many warps were left until the end while playing. Kudos to the artists with the pixel art rooms. They had a lot of character for each of the hololive members they represented.
