@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
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
@monorail Well, the overworld has a baba is you, but there's no way to actually do anything with it that I can see. I can destroy it, making baba not me, but then I don't have any ability to do anything else. I think? Let me look at that.
re: your first hint, definite spoilers now
@monorail Finding a way to get Level Is Flag seems like a straightforward thing to do, actually... Let me see if I can do that anywhere.
re: your first hint, definite spoilers now
@monorail Aha! That was a rather interesting way to achieve it, but I got Level Is Flag. Now to explore this new place.
a hint for an optional task, if you want it
@Rosemary there's a sort of side-objective you can achieve in the secret level, in addition to just winning it and getting the dandelion
funnily enough, it's the same problem. why are you allowed to move there? but asking that question doesn't really help you solve it
the actual hint is that it's basically impossible to solve it any way other than "by accident", but it's designed to be extremely easy to solve by accident
re: a hint for an optional task, if you want it
@monorail Orb Is Bonus, yes? I did discover Hide.
re: a hint for an optional task, if you want it
@Rosemary ah okay, cool
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?
