@Rosemary i haven't beaten every puzzle but i've beaten a lot (and gotten to the end) and have had practice giving hints that are useful without just spoiling the solution
@monorail Would you mind overmuch if I asked for a few? We've gotten to the end--beaten A Way Out?, anyway, which I assume is the end but there could be a secret extra part--but a few of the puzzles have me completely stumped.
@Rosemary i wouldn't mind at all!
your first hint
@Rosemary there's so much secret stuff that A Way Out? being presented as the ending is basically a joke the developer played on you. there are whole worlds of more puzzles
your first hint
@Rosemary you've almost reached what the discord server considers the "late game"
re: your first hint, definite spoilers now
@monorail I couldn't even hope to beat A Way Out? the first time I got access to it; there were too many unfamiliar words. So I've unlocked worlds up to the mountaintop and the chasm, and I have found the one secret level that you can get by using Level Is Baba--which, let me say, was quite an amusing twist to be able to do that! I'm not sure if that's what you consider the late game or not.
re: your first hint, definite spoilers now
@Rosemary oh good, you've gotten , you're very very close
by default (say, if you were in an empty level with just baba in it), none of your arrow keys would do anything. why are you allowed to control baba on the overworld?
re: a hint for an optional task, if you want it
@Rosemary ah okay, cool
