The Basement Collection is on Steam and was part of a Humble Bundle. I have played most of these games on flash, and I presume they are all available at the usual flash sites. Aether is one of these, with a spirit evoking The Little Prince, in which you go make some planets happy.
Aether has the obvious achievement for completing the game, and then it has achievements for finding things in outer space. Five of them are obvious: the planets’ moons. Then there are eight other things in space. You would have no reason to know they exist unless you looked at the achievements or happened to find one. They are … somewhere. Just go wander in space for a while. There must be a methodical way to explore space, and once something is found you can direct others by reference to its location relative to the other planets. Until you stumble upon one of the floating things, however, you are just flying blindly about. While peaceful, this is perhaps not the highest quality gameplay to incentivize.
“Cheating” is defined collaboratively in gaming. It is not always obvious what is a bug or intended, and if not intended whether there is any negative connotation to doing something. In a puzzle game, looking up the solution is pretty clearly cheating, but you may also want to check with others for hints or “am I even going in the right direction here?” Because sometimes you are and the game is just not cooperating. So the achievement is for finding things in space, where wandering is the spatial equivalent of grinding mobs; there is no reason why The Crybaby should be in that bit of outer space, so you just keep going until you find them all (or don’t).
Looking up the locations is pretty clearly cheating, but I don’t know if the task is respectable enough to merit any negative connotation to that. In a game with trial and error gameplay, I see no shame in just seeing which combination you are supposed to find by random guessing or brute force. But at least you do not run out of air and die in space if it takes too long to find one.
It’s like Explorer content…
