Three years ago, I wrote a joke review for this game just saying "Superbrothers: Sword & Sworcery EP is an indie game", with the joke being that it looked like the samey pixellated trash that was flooding the indie scene at the time. But now I actually got around to playing it, and I've found that it's actually exactly what I expected it to be.
You don't really do much in this game. Your goal in each area is to find the sprites "hidden" in the area, though they aren't particularly difficult to find. Then you do a quick "puzzle" ranging from things like sliding ducks to their mother to engaging in trial-and-error to find the correct sequence of clicking on trees. You do this a few times and then occasionally fight a boss that plays out kind of like the first Ganondorf fight from Ocarina of Time, where you deflect a missile attack back and forth until it hits it. You meet two characters along your journey and you can see their thoughts, along with your own, in the megatome (a magic book that you find early on), and they're interesting enough to not make you feel like you wasted time reading them but they rarely go beyond that level. The game disagrees, of course, and even if you tell it that you don't want to participate in its twitter functionality early on it's still going to put a tweet button beside every line of dialogue and constantly remind you that social media is going to play an important role in the game (spoilers: it doesn't, at least as far as I could tell).
If the controls were changed at all from the iOS version beyond letting you use your mouse, I couldn't tell. Almost everything is done by clicking and holding, or clicking and holding and sliding, and other things you would expect from a touch screen game. I didn't think it was possible to make a simple point-and-click interface unintuitive, but they've proved me wrong. You can move by either double clicking the area you want to move to or holding and sliding, but holding and sliding produces a constant humming sound that goes against the music, which is presumably the whole point of the game. The music is admittedly good, particularly one part where you can listen to the composer play the guitar while clicking on things in the environment to make your own rhythm alongside him, but a significant portion of it seemed to just be ambiance. It set the scene well, but it isn't something that I'd want to listen to outside of the game, though I'm not sure if that was the point or not.
So in the end, my review 3 years ago was probably better left unchanged anyways. In the time it took you to read all this you could've done something else that takes a minute or two to do, and you still probably wouldn't have touched this game either way for $8. Maybe we'd all be better off if I had never returned to Superbrothers: Sword & Sworcery EP after all these years.
