I would think 100% would mean collecting every memory + beat voden (Personally).

As for a glitchless, a lot of our OOB certainly cause a barrier to entry, especially things like flippy skip and Ludomir skip. I know my very first run of the game was over 5 hours long, spending over an hour on each flippy skip. My dislike for that skip is what motivated me to find my alternative.

Depending on how people feel, 100% may be able to help with the OOB problems. Since we will need the seals to reach all of the memories anyway, we wont be able to skip Draga D1. Hence no flippy skip.
