We've said "so long" to gay Bowser in Super Mario 64, the first of the games in this 12-game randomizer to be cleared, right after the 40 hour mark.
I don't have the "release on finish" setting on, so this wasn't a deluge of free stuff. I may still need to return to Mario 64 for more items. Even so, when I left off last night, all the games were unstuck. I'm planning to resume the quest in an hour or so.
Celeste 64 is the second game to finish. I got a lot of help from chat, given that I hadn't played Celeste 64 before this!
(don't worry I won't do a spoilery headline for Tunic)
